How to Access Your Plesk Mailbox in Gmail

This guide shows you how to read and send mail from a Noiz mailbox, hosted in Plesk, using Gmail. It is written for people who already live in Gmail all day and would rather not run a second inbox for their domain mail. Gmail can do this, but there is one thing to understand before you start, because it decides which of the two routes below you should take.

The Gmail app on your phone is the only route that connects Gmail directly to your Noiz mailbox. The app uses IMAP, which keeps everything in sync properly. Gmail in a web browser used to collect mail from other providers over POP (“Check mail from other accounts”), but Google is withdrawing that feature: it no longer accepts new setups, and existing setups stop working in January 2027. Google is also ending “Send mail as” for non-Google addresses in January 2027. For Gmail on the web, the route that remains is to have Plesk forward your mail to Gmail, which is what Google itself recommends.

Last reviewed: 23 September 2026, against Gmail on the web and the current Gmail mobile app, with a mailbox hosted in Plesk on Noiz. This guide is written for Noiz hosting and is kept current against Gmail. It complements, and does not replace, the official Google documentation linked below. Google changes the Gmail settings screens regularly: where a screen differs from what is described here, the field names and the values you enter stay the same even when their arrangement moves.

Official Documentation Reference

• Learn about upcoming changes to Gmailify and POP in Gmail (Google): Google’s announcement and timeline for the end of POP collection, and its advice to use forwarding or the Gmail app instead.
• Send emails from a different address or alias (Google): the “Send mail as” feature, which lets you reply from your own domain in Gmail on the web until Google withdraws it for non-Google addresses in January 2027.
• Add another email account in the Gmail app (Google): the mobile route, and the only one that offers full IMAP.
• Setting Up Mail Forwarding (Plesk Customer Guide): the Plesk setting used in the web route below.
• Access your mailbox (Plesk Customer Guide): Plesk’s overview of the ways to reach a mailbox. It does not cover Gmail, which is why this guide exists.

Prerequisites

• The mailbox already exists on the Noiz mail server. If you have not created it yet, do that first: see How to Create an Email Address in Plesk.
• You know the full email address, for example you@yourdomain.com, and its password. The username for Noiz mail is always the full email address, never just the part before the @. If you have lost the password you can reset it from Plesk: see How to Change an Email Account Password in Plesk.
• You can reach the mailbox at least once through Plesk webmail. The web route below requires you to open a verification message that Google sends to the mailbox, and webmail is the simplest place to read it.
• A Gmail account. A free @gmail.com account is enough; a Google Workspace account works the same way.
• Your domain’s mail is hosted at Noiz. If the domain was pointed to Noiz recently, allow DNS changes time to take effect before mail.yourdomain.com will resolve.

Understand What Each Route Gives You

Read this section before you choose. It is short, and it saves undoing a setup later.

	Gmail app (IMAP)	Gmail on the web (forwarding from Plesk)
How it works	Connects directly to the Noiz mailbox	Plesk sends a copy of each new message to your Gmail address
Folders on the server	Visible and in sync	Not visible. Only mail that arrives after forwarding is switched on reaches Gmail
Read, deleted and filed status	Syncs both ways	Does not sync back to the server
New mail arrives	Promptly	Promptly, as it is forwarded
Sending as your own address	Handled during setup	Needs Gmail’s “Send mail as”, which Google ends for non-Google addresses in January 2027
Accounts you can add	Up to five other addresses per Gmail account	Set up in Plesk, not in Gmail

The practical rule: if you want your domain mail to behave like a real mailbox, use the Gmail app route. Use the web route when you specifically want everything funnelled into one browser inbox and you accept that it is a one-way copy.

Many people end up doing both, and that is fine, but only if the Noiz mailbox keeps its own copy of each forwarded message. That setting is covered below, and getting it wrong is the single most common way people lose mail in this setup.

The Noiz Mail Settings

These are the settings a Noiz mailbox uses in any mail program, Gmail included. Wherever you see yourdomain.com, replace it with your own domain.

Setting	Incoming, IMAP (Gmail app)	Outgoing, SMTP (Gmail app and Send mail as)
Server / hostname	mail.yourdomain.com	mail.yourdomain.com
Port	993	465
Encryption	SSL/TLS	SSL/TLS
Username	Your full email address, for example you@yourdomain.com	The same
Password	The mailbox password	The same

Two points that catch people out:

• The username is the whole address, including @yourdomain.com. A username of just you will fail to authenticate.
• Noiz uses SMTP on port 465 with SSL/TLS. Gmail’s “Send mail as” screen offers 465, 587 and 25; choose 465 and Secured connection using SSL. Do not use the unencrypted ports (143, 110 or 25), which Noiz mail does not accept.

Route 1: The Gmail App on Your Phone (IMAP, Recommended)

This is the better route. The Gmail app treats a Noiz mailbox as a real IMAP account, so folders, and the read or unread status of every message, stay in step with Plesk webmail and any other device.

1. Open the Gmail app.
2. Tap your profile picture at the top right, then Add another account.
3. Choose Other (IMAP) from the list of account types. Do not choose Google, Outlook or Yahoo.
4. Enter your full Noiz email address, for example you@yourdomain.com, then tap Next.
5. If you are offered a choice, select Personal (IMAP).
6. Enter the mailbox password, then tap Next.
7. On the Incoming server settings screen, confirm the server is mail.yourdomain.com, the port is 993 and the security type is SSL/TLS. Correct them if the app has guessed differently.
8. On the Outgoing server settings screen, set the SMTP server to mail.yourdomain.com, the port to 465 and the security type to SSL/TLS. Leave Require sign-in ticked and confirm the username is your full email address.
9. Tap Next, choose your sync preferences, and finish.

Your Noiz mailbox now appears alongside your Gmail account in the app’s account switcher. Send yourself a short test message and reply to it, to confirm that sending and receiving both work.

The account you have just added is a normal IMAP account, so the same settings work in any other mail program if you later decide to use one. Thunderbird and Microsoft Outlook are both covered separately.

Route 2: Gmail in a Web Browser (Forwarding From Plesk)

Gmail on the web cannot connect to a Noiz mailbox over IMAP, and its POP collection feature is being withdrawn (Google’s timeline has the dates). Google’s advice for the web is to forward mail from your other provider, and in Plesk that is a setting on the mailbox. This route is two jobs, and you need both halves if you want to reply from your own address.

If you already collect your Noiz mail with “Check mail from other accounts”, it keeps working until Google switches it off in January 2027. Move to forwarding before then. Mail Gmail has already collected stays in Gmail.

Part 1: Forward Your Mail to Gmail (Receiving)

In Plesk, open Mail, click the mailbox, go to the Forwarding tab, switch on forwarding and enter your Gmail address. How to Set Up Email Forwarding in Plesk walks through it, and the Plesk guide Setting Up Mail Forwarding is the reference.

Gmail is stricter with forwarded mail, so if forwarded messages go missing, check Gmail’s spam folder and see the troubleshooting in How to Set Up Email Forwarding in Plesk.

Keep a copy in the Noiz mailbox, unless you are certain. Plesk lets you clear the Mailbox checkbox so that forwarded mail is not stored on the server. If you do that, your mail exists only in Gmail: it no longer appears in Plesk webmail or on your phone, and it is not covered by mail backups on the server. Leaving the mailbox switched on costs you nothing except mailbox space, and it is what almost everyone should do.

Part 2: Send From Your Own Address

Gmail’s Send mail as feature lets you reply from you@yourdomain.com through the Noiz mail server. Google withdraws it for non-Google addresses in January 2027. After that, replies from Gmail on the web go out from your @gmail.com address, and the Gmail app route above is the way to send as your own address.

Until then, add the address in Gmail under Settings, See all settings, Accounts and Import, Send mail as, following Google’s steps. When Gmail asks for the SMTP server, use the Noiz values:

• SMTP Server: mail.yourdomain.com
• Port: 465
• Username: your full email address
• Password: the mailbox password
• Select Secured connection using SSL

Google then sends a verification message to the mailbox. Open it in Plesk webmail, or in Gmail once it has been forwarded, and click the confirmation link. To send from the address by default, click make default beside it on the Accounts and Import tab. Google’s page also covers setting the reply-to address.

Things Gmail Does Not Do Well With a Custom Domain

None of these are faults in your mailbox. They are how Gmail works, and knowing them up front prevents a support ticket later.

• Forwarding only covers new mail. Messages already in the Noiz mailbox, including anything filed into folders, are not copied to Gmail. Only mail that arrives after you switch forwarding on is sent on.
• Nothing syncs back. Reading, deleting or filing a message in web Gmail changes nothing on the Noiz server. If you also use webmail or a phone, the same message will still be sitting there unread.
• Your mail is copied into Google’s infrastructure. Anything forwarded to Gmail is stored on Google’s servers and processed there. If keeping your business mail on Noiz infrastructure matters to you, whether for privacy, data residency or POPIA reasons, use Plesk webmail or a mail client such as Thunderbird, both of which talk to the Noiz server directly.
• Sending still goes through Noiz. Because “Send mail as” is configured against the Noiz SMTP server, your outgoing mail is authenticated as your mailbox and carries your domain’s reputation, which is what you want for deliverability. Do not be tempted to remove the SMTP settings so that Gmail sends on your behalf instead.

Troubleshooting

Symptom: “Authentication failed” or “Username and password not accepted”. Almost always the username. It must be the full address, you@yourdomain.com, not you. Confirm the password by signing in to Plesk webmail with the same credentials; if webmail rejects them too, reset the mailbox password in Plesk.

Symptom: “Could not connect to server” or the request times out. Check the port and the encryption together. IMAP must be 993 with SSL/TLS, and SMTP must be 465 with SSL/TLS (“Secured connection using SSL” in Send mail as). A mismatched pair, such as port 465 with no encryption selected, fails in exactly this way.

Symptom: the server name is not recognised. Confirm that mail.yourdomain.com resolves. On a domain recently pointed to Noiz, this can lag behind the rest of the DNS changes. The mail server hostname from your Noiz welcome email always works and avoids the certificate warning described below, so use it if mail.yourdomain.com fails.

Symptom: Gmail warns that the server’s certificate does not match mail.yourdomain.com. The settings are right; the certificate belongs to the Noiz mail server’s own name. Use the mail server hostname shown in your Noiz welcome email as the server name instead, and the warning goes away.

Symptom: the verification message never arrives. Look in the mailbox directly through Plesk webmail, and check the spam folder there. Google’s verification mail is sent to the mailbox itself, so it is there even when forwarding is not yet set up.

Symptom: replies go out from your @gmail.com address. The “Send mail as” half was not completed, or the domain address was never made the default. Return to Part 2 above. From January 2027, Gmail on the web no longer offers Send mail as for non-Google addresses, so use the Gmail app route to send as your own address.

Symptom: mail has disappeared from webmail and your phone. Either the Mailbox checkbox was cleared when forwarding was set up in Plesk, so mail is forwarded without being stored on the server, or an older Gmail POP collection was set up without “Leave a copy of retrieved message on the server”. Switch the mailbox back on in Plesk, or remove the POP collection in Gmail, to stop further losses. Messages already collected still exist inside Gmail and can be forwarded back to the mailbox, but they are no longer on the server.

Still Stuck?

If the mailbox works in Plesk webmail but will not connect from Gmail, the problem is in the Gmail configuration rather than the mailbox, and the settings table above is the place to start. If webmail will not accept the password either, the mailbox itself needs attention. Open a ticket from the Noiz client area with the address you are configuring, the route you chose, and the exact wording of any error Gmail showed you, and Noiz support will pick it up from there.
