Mailman has been working great for several months until I made a couple of changes on the server. I had been getting tons of mail errors because the hostname was actually an ALIAS according to DNS, so I changed the hostname to the CNAME and stopped getting the errors. Around that same time, I upgraded to RedHat 6.0. Somewhere along the line, I started getting this error everytime anyone tries to post to any of our lists:
----- The following addresses had permanent fatal errors -----"|/home/mailman/mail/wrapper post be-install" (expanded from: <be-install@techops.rfa.org>)
----- Transcript of session follows ----- sh: wrapper not available for sendmail programs 554 "|/home/mailman/mail/wrapper post be-install"... Service unavailable
Reading between the lines :), it appears that for some reason sendmail is no longer allowing wrappers. Any ideas?
