So I am setting up the WebAccess for a Abonnement right now and I am trying to setup all settings so that the client has no insight to FTP nor any other hosting related data but mail only!

So the client should be able to manage mail accounts solely.

like to be able to specify a date and time an email auto-reply is started and finished.

Allow greylisting control individually per user, while maintaining the control by domain option.

As mentioned in http://forum.odin.com/threads/outgoing-email-limits-is-there-away-to-take-out-emails-sent-within-the-distribution.333512/#post-783419, we see that mails sent from one mailbox to another even in the same domain are taken into account for the email limit feature.

Such situations rarery arise from a stolen password or compromised clients which typically send spam to the outside world. And on the hand disturb some automatic internal tools programmed by the clients that do send mass mailings for internal processing.

Therefore we would like to have a way to out specify scope of the outgoing email limits either for everything, out-of-server emails or out-of-domain-or-subscription emails.

Free mail providers as Google, Microsoft and others want to verfify if you may send as by logging in to the smtp server.

Please add functionality to configure general email filters in Plesk.
The same functionality is implemented in cPanel:
https://documentation.cpanel.net/display/CKB/How+to+Configure+Mail+Filters

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

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.

For now SpamAssassin on Plesk for Windows does not add any headers to mail messages which were processed by it and not identified as spam. It would be good feature to add header showing that SpamAssassin actually processed this messages to all mail messages, even not spam one.
This could be helpful in order to monitor SpamAssassin functionality to understand if it works in general or not. Plus, some Spam checkers may show that mail inside mailbox were not checked at all, which is concerning.

In order to comply with RFC3834 the auto replay function should consider the X-Auto-Response-Suppress header. Also not replaying to mail with Auto-Submitted: auto-generated would be nice.

As SPF/DMARC implantation grows, users who forward emails to gmail/hotmail etc are causing server IPs to become blacklisted and also emails are bouncing. The forwarding server is not an authority to send for the original sender, and also forwarding spam is reducing the reputation of the server IP.
Users should use IMAP/POP collection , not forwarding, so we should be able to disable external forwarding. The box for forwarding should only accept email address within the local subscription domains. Easy to validate.

Add alert tag to message body for external emails:
The tag can be " CAUTION ! This email originates from outside the organization "

Any kind of wildcard mail aliases (regex and/or /?) would be highly appreciated in order to realize a "allow form all but anything like..." handler. Example: Ban all info-@domain addresses.

I had somenting similar at my old provider but not with new one using plesk. Now I need to insert dozens (hundreds) of addresses one by one...

If there is already a way to realize something similar I was not able to find it (or my provider did not enable it)...

The antispam filter could accept more than 100 addresses

I suggest
Currently, the whitelist for each mail account is stored as individual lists. In groups (families, small businesses, clubs, etc. ) these lists are time-consuming to maintain. It is easier to maintain these as a matrix. So I suggest to keep the TAB "whitelist", but to link to a single central matrix file.

Please add functionality to forward an email to non-existent user to the sender on the email in example.com > Mail Settings > What to do with mail for non-existent users.

It would be nice if a Preflight check were there. Check SPF Record, Forward and Backward DNS lookup, Send a testmail to mail-tester.com and parse the result to have ideas why own mail are spam....

Allow a@example.com only to send mail to example.com

if smartermail is local install you can create a SSL for webmail. This doesn't work with remote smartermail.

I would like plesk to introduce this so some kind of agent is running on the server so Plesk can communicate with IIS on the remote web server to copy SSLs and bindings.
