[Mailman-Users] stat=unknown mailer error 2

[Aaron Schubert]

When sending an email message to a test list on our mailman list server I receive the following error in the sendmail maillog.  Here is the maillog entry.

Jun 21 13:55:50 listserv1 sendmail[4764]: l5LItoG2004763: to="|/usr/local/mailman/mail/mailman post unixtest", ctladdr=<unixtest at internallistserv> (8/0), delay=00:00:00, xdelay=00:00:00, mailer=prog, pri=30989, dsn=5.3.0, stat=unknown mailer error 2

I am not sure what is happening but it looks like the error is when it tries to post.  Does anyone know what the stat=unknown mailer error 2 means and how to correct it?  Any help would be appreciated.
