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!

Please add functionality to access webmail from Plesk interface without using a password.
The same functionality is enabled in cPanel. Please see section "Access webmail from the cPanel interface" of documentation:
https://documentation.cpanel.net/display/CKB/How+to+Log+in+to+Your+Server+or+Account#HowtoLogintoYourServerorAccount-AccessWebmaildirectly

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.

Ability to change settings in the mail autodiscover - for example, to set the mail server that will be set in the mail client.

When installing Plesk with MailEnable, by default Plesk removes MailEnable logfiles every 24 hours.

According to this KB (https://support.plesk.com/hc/en-us/articles/115001102353), this functionality is made in purpose to optimize mail statistics, but this is not acceptable.

Additionally, you are offering the possibility to apply this workaround (https://support.plesk.com/hc/en-us/articles/213397889), but this workaround is not valid for us because we don't want to customize the FTP and HTTP logs location and we have the log files in different disk volumes.

Please, provide the possibility to configure the log rotation settings for MailEnable respecting our hosting company needs.

I have a domain which is an alias of another domain.

I have mailboxes created on the main domain, but now we want that the From Header on outgoing mails will be the alias one (username will be the main domain as usual).

An option to choose IP for outgoing mail on domain basis.

For now, only below options available:
- all the domains send from particular IP
- each domain uses its IP address

This feature is for use case when one or several domains can send through one IP address, and the others through another one.

It should be managed independently of web hosting IP address.

Currently all mailbox passwords(MailEnable) are stored in AUTH.TAB in plain text that is not secure.
MailEnable has an option to enable password encryption in AUTH.TAB

Enable / Disable Webmail Access not for All Domain but for selected Mail Users

When installing Plesk with SmarterMail, the mailbox usage stats are calculated, however, the mail traffic usage stats (IMAP/POP3 + SMTP) are not calculated.

It would be really useful that Plesk would calculate mail traffic usage for when SmarterMail is being used, otherwise, we cannot monitor the traffic usage made by our customers nor limit it.

Prosody is a xmpp/jabber Server. You can build your own part of a dezentral messenger network like Whatsapp - but with you data in your hand.

Cannot even open inbox. Please take me back to the old dashboard.

Please add functionality to configure general email filters in Plesk.
The same functionality is implemented in cPanel:

I've installed 1.4 manually and it works without problems.

Implement push notifications to iOS devices from mail server.

Here are details of what I mean: using a patched version of Dovecot and a small Perl script, it's possible to get native Apple push notifications for new mail using the stock iOS mail client. This is accomplished by mimicking Apple's XAPPLEPUSHSERVICE IMAP extension for Dovecot used in macOS Server, whose source code is published on the Apple Open Source website. See more details here: http://bit.ly/2H8NERJ

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

Plesk should be able to create email groups. Most email servers, including the MailEnable that comes with Plesk, implement email accounts, email lists, and email groups in quite different ways. Plesk allows us to create email accounts and mailing lists, but it does not allow us to create email groups. Instead, to get the result that an email group offers, in Plesk you need to create an email account, disable the email box and set up forwarding to addresses that are part of the "group" . This is a little weird.

As a Plesk administrator, I would like to set the sender email addres for PHP scripts.
