[CentOS] Recommendations for webmail client on EL8

Hi all,

I'm still trying to find solutions to replace some aging EL6 and EL7 systems.

This time I'm looking at email. Postfix and Cyrus-IMAPd are not a problem
and also additional things like DKIM are fine. However, I'm wondering what
to use to replace good old squirrelmail with.

We had a heavily patched squirrelmail with lots of nice things like
avelsieve plugin. Since squirrelmail is dead and unable to run on newer
PHP, I'd like to use some other tool instead.

I was looking at Roundcube but it seems difficult on EL8 because a lot of
PHP stuff is missing and not available as RPMs. I guess the same is true
for the python things needed for Mailpile. In the end my list only
contains Cypht, Rainloop and Afterlogic Webmail lite.

Is there anybody running webmail on EL8? Can you make a recommendation on
a certain tool?
