For some reason, the mail for 1 specific mailinglist doesn't get distributed. It worked fine before, and no changes have been made.The mailman3 debug log shows that mailman keeps attempting to distribute the mail.The mailman3 error log show that there is a connection failure to port 25.A tcpdump however shows that there are *NO* further connection attempts on port 25 (postfix) to distribute this mail.Also after stopping and starting mailman3 again, no further connection attempts to the mailserver (postfix) are being made for this mail.Using qfile, the pck file of this mail looks fine.
New emails on this specific mailinglist are not distributed either.For all other mailinglists on this server, and which are on the same domain, there are no problems.
Does anyone know how to get this mailinglist functioning properly again, and what is causing this issue?Below are the relevant extracts from the log files for the particular case.
