I’ll mention another issue we had, similar to this.

Initially, we set up our virtual list domains as CNAMEs for the list server hostname.

List.auckland.ac.nz CNAME Sympa.auckland.ac.nz.

Sympa.auckland.ac.nz A 130.216.191.21

Sympa.auckland.ac.nz MX gateway.auckland.ac.nz.

This worked for mails sent from our Exchange system ; however it turned out that sendmail under linux will ‘canonicalise’ the hostname by default on the way out, so ‘address@concealed’ gets silently changed to ‘address@concealed’ before it even reaches you. This causes control messages to hit the wrong robot, and even some lists to go to the wrong place.

In the end, we had to create multiple A and MX records for the virtual domains; IE new A records, all pointing to the same IP, for each and every robot on the server.

List.auckland.ac.nz A 130.216.191.21

List.auckland.ac.nz MX gateway.auckland.ac.nz.

Sympa.auckland.ac.nz A 130.216.191.21

Sympa.auckland.ac.nz MX gateway.auckland.ac.nz.

This solved the issue with misdelivered message from linux servers; it may be related to your problem as well.

thank you very much.

turns out that the alias for sympa was placed in /etc/alias.local as lists.example.com, so I changed it to example.com, and now the moderation goes to the right robot.

thanks for your help.

I’ll add an echo to what David said. I think it’s your aliases configuration.

We have about 8 robots on our server; initially I had exactly the same issue (with requests going to the wrong Sympa@<robot> address and being marked bad). I needed to make sure there were appropriate Sympa-<robot> aliases defined, and that our aliases.pcre was set up correctly. Then all worked.

I also had some issues because I’d set Sympa@<robot> to be a listmaster, and so it was receiving notifications which were processed as commands, generating error notifications to listmaster... you get the idea.
