Free mail server with reports?

Question

linux

Hello. The problem is the following: you need to start a mail server + phplist with minimal reporting: how much was sent per day\day\month, how much was sent, how much was returned. zimbra and onlyoffice are not suitable. they are too demanding, you need something easier like iredmail, but it has reporting and statistics only in the pro version.
If you have any options please let me know. Requirements: imap web-interface (preferably) minimal statistics reporting, highly desirable.
Thank you.

Exim+Dovecot+rainloop.
Exim draws quite good reports based on logs.
