It would be a great idea to be able to import mail for individual email accounts via POP3 from other servers.

This would be great for customers migrating to you so that they can keep all their email.

Would just need fields such as:
-Hostname
-Username
-Password
-Port
-Encryption

Add Sogo as a webmail alternative in Plesk.

Sogo share your calendars, address books and mails in your community with a completely free and open source solution

Sogo is a great webmail solution and provides native Microsoft ActiveSync support. Mobile devices such as Apple iPhone, Android, Windows Phone, and BlackBerry 10 can fully synchronize emails, contacts, events and tasks with SOGo.

autodiscover for email settings for linux and windows

We have many support requests from our customers (non technical) to search logs and find if a message was sucessfull delivered and consume much from our support.

If the customer could search logs from a specific sender ou destination, filtering by date, will be great for us.

It would be useful to be able to configure auto replies so that they start automatically on a specific date.

If I don't want to forget to set it before leaving.. or i'm sure there's many reasons!

I would like to use an E-Mail address as an outgoing E-Mail address with no postbox behind it. All E-Mails should be forwarded to another E-Mail address.
Currently you can set up forwarding but if you check "Use postbox" than the mails will be kept on the server although they have been forwarded. If you uncheck it, it is impossible to send emails from that address.

So please add at least an option to delete mails after forwarding them.

The ability to empty a users emailbox without deleting the account and recreating would be great.

There is an spam filtering option to "Move to spam folder XXXX" on Linux, but not on Windows (Plesk 11+).

Unfortunately, horde doesn't work so well and every time when a message with broken header arrives, horde displays "Invalid Address" and no subject to all inbox messages. The described fix in https://kb.plesk.com/en/121175 doesn't work in this cases, forcing us to find the broken message manually (or scripting something to do the dirty job).

This feature should exists in Windows env as in Linux.

There is relatively new anti-spam tool - Rspamd. I think, it worth to be integrated with Plesk as an alternative to SpamAssassin. It shows better performance as the author says here http://rspamd.com/misc/2016/03/03/rspamd-performance.html

Possibility to configure separate relay Server for specific Domains., or local / direct delivery.This is asked by customers very often in past.
Usefull if you have a smarthost for outgoing and incomming mails (Anti-Spam, -Malware, etc.).

Hi,
plz add mailman 3 as mailinglist software.

This would allow you to see mailboxes that are no longer in use.

email adresses for subdomains are necessary - why this is not implemented as a standard

Sometimes is useful check the details about POP3/IMAP/SMTP traffic for a single email, to look and find problems.

Add Plesk Panel UI for configure outgoing Mail Server.

""In Plesk for Linux with the Postfix mail server, you can change the IP address used for sending mail. Also, if your server sends mail from domain IP addresses, you can specify which name will be used as a host name in SMTP greetings.""

So a UI where the Admin of Plesk Server can, change the settings for outgoing Mails.
Send from domain IP addresses and use domain names in SMTP settings.

All incoming/outgoing mail for a certain domain is copied automatically to a different inbox within that domain.

I would like to be able to create own e-mail addresses for Domain Aliases. Let's say i have example.com as domain and add example.net as alias, now i would like to create e-mail adresses for example.net (alias domain) only which are NOT available on example.com and vice versa.

If i add a new domain in a subscription, greylisting is automaticly activated, just because it's enabled on the server.

It would be much better if customers have to activate greylisting manually in their settings, like the spamfilter.

A workaround with Event Manager is possible but a bit inconvenient.
