We have a cluster of mail servers, one of which we have upgraded to 1.6-Release (from 1.2) and then subsequently did a fresh install of 1.6 on after the issue first arose.
In essence, using the supplied sendmail and having the connected sendmail session issue a rset command results in that sendmail process hanging (only by issuing the telnet ^] command to get to a telnet prompt and issuing quit can the session be killed). If instead of an rset command the quit command is issued, the session will end (i.e. the telnet session terminates) but the sendmail process with "quit" appears in the process list and will not go away unless killed. Has anyone seen this odd behavior? At first I thought it was due to a milter, so I removed it from the .mc file and rebuilt sendmail.cf but no change in socket behavior. How can I help in terms of troubleshooting? Sven
