In a perfect world, no, send/post should never hang. But we never got good details on what was going wrong there. I believe you said running it with -snoop returned no messages, it still was silently hung. If you're using the "smtp" or "sendmail/smtp" MTAs, there should never be a hang. There may be a network timeout along the way, but you should see some notification with -snoop as to what it is doing (the timeouts could be up to a few minutes, depending on the operating system). I could maybe see problems contacting a DNS server, but you would think that would show up in others ways (and even then, eventually you'd get an error message). If you're using "sendmail/pipe", all bets are off. If you have a setup which uses a custom postproc, again, all bets are off. --Ken
