It would be really handy if we could, via Plesk panel or some cli utility, o switch from Maildir to mdbox as mailbox storage format and enable alternate storage for old emails. This way we can optimize the disk usage by using the fast storage media for recent emails, while the old stuff can go on a slower, cheaper media. Will also help a lot in growing our mail customer base without forking out ridiculous amounts of money for expensive fast disks arrays to keep up with the growth rate.

To use Sympa instead of Mailman

Roundcube for Windows

There is a Mail Importing feature in Site Import extension, but it is possible only to migrate emails one by one. It would be great if there is an ability to migrate a couple of mailboxes at once.

Hello,

Is it possible to add Rainloop as a webmail client?

Since roundcube next isn't coming anytime soon I think this is a great alternative.

Kind Regards,

When DKIM is activated, the key isn't added when you use the PHP mail() function, for example if you have a contact form on the website. Please add because this generates false SPAM-detection problems. Google for example thinks it's strange that sometimes the DKIM key is added and sometimes not. Please keep in mind that this should work with an external DNS-service too.

Some mails could not be received due to the fact the Postfix 2.8 and higher in Plesk uses only TLS encryption, when senders use other encryption methods. Manually updating main.cf directly on the server (as discribed in https://plesk.zendesk.com/hc/en-us/articles/213386889) is not always an option since the main Postfix configuration file may be overwritten by any Plesk update. In order to avoid potential issues with non-delivered mails it is required to make SSL/TLS encryption on port 587 optional, not mandatory.

For better SPAM Protection it would be nice to add an Option to let the Mailserver check, whether senders Domain is existing or even not.

I got Mails from "Domain.xyz" wich is of Course no valid TLD.
"Reply-To" is of Course an valid Mail adress.

On request, my Data-Center told me they could activate that Option, but while Plesk is Controlling that config, on next Plesk update the Change gets lost.

So: Could you add in Plesk that Feature as an Option?

Add the count of messages in the postfix mailq to Advanced Monitoring and Grafana. Then we have the option to get alerts if mailq goes up, in case of spam events!

Restrict what attachments are to be filtered by Mail server. Example
All Domain > Block Extension > exe,jar,rar,gzip

According to https://support.plesk.com/hc/en-us/articles/115000786914-How-to-enable-SpamAssassin-spam-check-for-forwarded-emails-on-Windows when the option "Apply individual settings to spam filtering" is enabled, filtering of forwarded emails is not performed and additional steps are required.

Please, make it so that no additional steps would be required.

Currently, Plesk Premium Email can be enabled only for a subscription.
But Plesk Premium Email license differ by a number of users, so, to not exceed the license limit, it'll be handy to define which particular mailboxes on a subscription have the ability to use Plesk Premium Email

Don't send auto responder to adresses with "noreply" or "no-reply"

Details: SA should filter forwarded spam emails just after they delivered to the end-point mailbox and block the sender of spam messages.

Use case: One of our customer has uploaded files to his ftp server in a public internet cafe and his password was stolen. Afterwards there was a mass spam mail sending script on his webserver. Our server has been landed in black lists. It was very difficult to find and correct it.

DKIM - needed to import own keys

It is not fair solution that Plesk generate a private key, and i cannot extract and date them in a seperate Backup

Please let us import our own DKIM keys

Hello,
I miss the functionality of managing a blacklist of target email addresses in case you have a catchall email domain.
In most cases, the originator address of spam emails changes every time, but the target address is frequently used.
So with this functionality, I could drop out invalid recipient addresses, without giving up the setup to use catchall all emails <everything>@your-domain.
This is useful to register webshops or community everytime using a separate target email address to distinguish incoming email if they are valid or not.

Now, if you sent an email to 100 recipients, it counts only as 1 sent in Plesk Outgoing Limit. It should count as 100 sends.

In Plesk Windows, by default, mailing lists are created with the sender address of moderator instead address of mailing list.

So to fix the issue, and change the address of mailing list to mailing lists address instead moderator address, we need to acess the server via RDP, and change this configuration in MailEnable list settings.

I suggest to implement this feature directly in Plesk control panel.

It would be really nice, if you can ad a autoresponder funktion with additional features like

-startdate
-Timefunktion (start at 8.00 or finish 17.00 h)
-repeat function (example: every monday and tuesday)
-activation per app
-html in content area

Thanks
