Hallo, all! Today, I recognized, that mailman throws error like "... Recipient address rejected: User unknown in virtual mailbox table ..." One of my users informed me, that mailman does not work anymore, if she tried to send a mail to a list. Now, I found, that the files in /var/lib/mailman/data where touched during upgrade process. aliases is filled properly, but virtual-mailman was empty. I tried to fix it by doing a /var/lib/mailman/bin/genaliases, but virtual-mailman is still empty. of course, the lists are still persistent in the mailling list configuration of ISPConfig. So I filled this file manually with the correct entries (the scheme looks like this: listname@domainname listname, and so on, ten entries for each list) and did a postmap. Hope, that did the trick for now. But why, the upgrade damages the configuration? Thank you in advance, Ralf
Same problem and similar fix reported at https://www.howtoforge.com/community/threads/upgrade-to-3-1-breaks-existing-mailman-lists.74236/ .. looks like there is an issue open on it: https://git.ispconfig.org/ispconfig/ispconfig3/issues/4135
