Request to when a customer clicks to log in on the webmail it shows the options of webmail platforms he can select.

Example attached:

Please add functionality to configure redirection of single domain webmail.example.com to another URL

Currently, it is possible to apply it using the workaround:

https://support.plesk.com/hc/en-us/articles/360003509474-How-to-redirect-single-domain-webmail-example-com-to-another-URL

Add event in Plesk that will allow to suspend a domain when outgoing mail limit has been reached.

"JMAP is intended to be a new standard for email clients to connect to mail stores. It therefore intends to primarily replace IMAP + SMTP submission. It is also designed to be more generic such that it can be extended with contacts, calendars in the future (replacing CardDAV/CalDAV)." (http://jmap.io/)

Sounds good to have it ASAP it is released.

Add a Tag for the notification emails for the Public IP address of a server. If a server is using NAT when the <ip> Tag is used it shows the Private IP address in the Site Notification emails instead of the Public IP address.

Now i have to insert a mailadresse at each mailaccount-blacklist.
i think it easier to use, i im able to handle a whiltelist/blacklist for all mailaccounts

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

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

Add an option to set a delay to the Postfix auto-reply. Currently, it sents instantly.

To allow Plesk admin/domain owners to change the maximum message size limit set per domain or subscription.

We would like to make the emails to be sent from our Ticketsystem mail and not from the Plesk admin mail

Plesk admin should have control over all possible mail notifications sent by Plesk. For example, Plesk admin should be able to enable/disable notifications which inform that Plesk failed to generate web server configuration files. Some Plesk owners may already have checks and notification mechanisms in place for Nginx/Apache, as well as several other services.

It would be useful to be able to add domains to IgnoreMailFrom rule for DMARC check from Plesk interface.

It would be a good idea to be able to set mail filtering for emails with specific Subjects in Plesk Email Security extension.

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

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.

There is White List under Tools & Settings > Mail Server Settings, it is used by SpamAssassin.

MailEnalbe has also White List under Servers > localhost > Services and Connections > SMTP > Properties > Whitelist.

MailEnalbe Whitelist cannot be managed through Plesk.

It would be nice, to have ability to manage MailEnalbe Whitelist in Plesk interface

Hello,

Please add functionality to create webmail account in Plesk if an external SMTP server is configured:

https://docs.plesk.com/en-US/onyx/administrator-guide/mail/using-plesk-without-the-mail-server.72346/

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.
