My client we'll soon have Proxmox Mail Gateway in production, but he would like to replace its self-hosted email setup (now whm/cpanel) to something dedicated exclusively to handle emails: for sure many of you have experience with self-hosted solution, can you give us some hints/suggestion ?

thank you in advance
 
We have plain postfix/dovecot mail server, with local users. I guess it depends on number of users in your organization, but you could use something like mailcow, mailu or iredmail for easier administration.

thanks!

not many users (about 25), and no real need for webmail (they all use Thunderbird): only one domain; our main concern is protection from malware/virus/spam.

* https://mailu.io sounds pretty goods, thanks! (https://github.com/Mailu/Mailu )

* https://www.iredmail.org good too (https://github.com/iredmail/iRedMail/ )

* https://mailcow.github.io/mailcow-docs (and 5k stars! in https://github.com/mailcow/mailcow-dockerized )

Then I see

* https://github.com/mail-in-a-box/mailinabox

if anybody have some other advice.

I guess for easier maintenance is better to go for docker setup, isn't it?

As far as Proxmox Mail Gateway integration, which we no doubt want to put in front, it looks like we can choose any of the above https://pmg.proxmox.com/pmg-docs/pm...ation_into_existing_email_server_architecture but maybe some tool fits better? I mean, I see Proxmox mail gateway use ClamAV + SpamAssassin, so I guess would be better to have two different open source alternative tools inside the self-hosted email server, no?

I see for example that:
* mailcow have https://www.fuglu.org in addition for content scanning
* mailu has https://rspamd.com for spam filtering

cool, thanks, but, you see, we want to leave cpanel/whm 'cause we ended up using it only for emails: and it is now really offering too much for just what we need (so to avoid security issue due to what we actually do not use)
 
Just an update on our choice:

We opted for ISPConfig (thanks Filipe!)

As for the alternatives:

* iredmail: super, but the free version does not let you do anything, so totally useless: the resulting configuration (auto installer) is pretty complicated, so I think a bit hard to maintain
* mailinabox: seems not updated that much
* mailcow: too many features (probably good if you do not have pmg in front; then: container only (which was not our preference), plus website/doc with mixed german/english
* mailu: really good, but on docker (which we wanted to avoid)
* then https://modoboa.org which looks really great, has all the pros... they only issue we had was with installation (conflict with requirement with latest python in ubuntu/debian): I would strongly recommend it if you are handy with python/django.

btw: we did not use a plain postfix/dovecot mainly 'cause we needed a web interface to handle users (suspension, forwards, aliases), and also handle 3 domains (I think with one user a basic Webmin will be enough); the mailman included in ISPConfig also helped (we needed a couple of mailing lists)
