For those interested in Mailman support in Plesk, note that there might be some hope:

Please add Mailman3 support as customers still have mailman 2 lists in use.

mailman 3 with ubuntu 22.04 would be great with plesk.

AWS no longer offers a Ubuntu 20.04 LTS image for Plesk, meaning that if you build a new Ubuntu-based Plesk server from the AMI you have to have 22.04 and therefore can't have Mailman. Please urgently schedule this (or another mailing list) for implementation.

please add mailman 3 as mailing list software manageable from the Plesk panel as a 3rd party extension.

plz add mailman 3 as mailinglist software

If Mailman 3 will not be integrated in Plesk, can you please provide instructions how we can use the version provided by the OS? Just upgraded to Ubuntu 22.04, and the lack of mailman support is critical.

To be clear, migration is not necessary for my case, but the availability of the mailman 3 support is.

This is imperative! I just leased a new server for a mail server and now that I finally found this thread after two days of searching, I am screwed until this is implemented.

I lease a dozen Plesk licenses for nealry $1500/year and now I cannot change my mail server from the old Ubuntu 16 version, which is absolutely pitiful! I am not happy with this.

Seems that Plesk has dropped support for mailman at all. In regard of the recent pricing rise its a nogo. Its now even a problem to install via apt.

No mailist in Plesk, Which is very Bad for email services

Any news about mailman 3? Now that Debian has dropped mailman 2 from bullseye it's REALLY time for Plesk to support mailman 3 as well!

Hey together, Is there anything new about mailman3? we need it urgently!

Urgently YES.
And please fix the SSL-certificate-problem.

This feature request will never become outdated as long as we are using Plesk with Mailman, it will rather become more and more urgent. It would be interesting to understand your strategy with this request: postpone (until when), reject or propose another solution ? Thanks for taking your customers more serious.

on Ubuntu 18.04 the Mailman 2.* will install from plesk.
In Ubuntu we have an Paket mailman v 2.1.26
and an Paket Mailman3.
On command line install-component mailman3 will work?

... let me add that personally I would also gladly give up any migration mechanism from Mailman 2 to Mailman 3, if this is an impeding factor: just "package" Mailman 3 as a newly supported Plesk component, please.

Commenting "Admin" response of October 31, 2019:

I think probably all signatories of this request have a clear view about how Mailman is supported by Plesk (leveraging the version provided by the OS vendor), but I also think this is the very reason why this request have been brought forward in the first place, more than 3 years ago.

Of course I can speak only for myself, but I also think I'm not much off thinking that what we all would like to see is an OS independent implementation of Mailman 3, directly provided and supported by Plesk, together with all required components (Python, Django, Hiperkitty, Postorius).

I look forward for support of this clarification by all interested parties...

mailman 2.1 definately needs to be replaced or dumped. It's no longer a 'feature' to promomote in a hosting service its that dated and hard to use.

That would really be great. I have a huge problem with yahoos DMARC policy and only mailman version 2.1.12 which has no option to do handle this problem :)
