I have recently had a partial hard drive failure on my server. I installed CentOS 5.3 on a new hard drive and copied what I could from the old drive to the new, including, I think, everything that Mailman needs.
I can get into the web admin interface for my lists, see the various settings for them, see the archives, etc.
When I send mail to a list, however, it seems to go into a black hole. I get no response that there was a problem delivering the mail, the server's maillog shows that the message was received by the server, but the mail never seems to go out to the list. There is no message in the mailman/errors log.
Any suggestions of what to check would be most appreciated.
