| Subject: a mail error question
| What does these errors mean? Should I consider these as BOUCE's and kick
| the users out. I get lots of these errors and it appears that such errors
| are dragging my mail (filling up the mail queue).
| >421 trac.army.mil (ddn)... Deferred: Connection refused by TRAC.ARMY.MIL
| >421 cts.com (ddn)... Deferred: Connection timed out during user open with
Deferred says that it will be held in the sendmail queue and tried again
later. The 421 means that sendmail either couldn't connect to the
destination host, or that the destination host found out it needed to
shut down in the middle of the transaction (e.g. system reboot). I
wouldn't kick the users out unless it became a regular problem with the
same users. If it was a problem I'd try to find out why the connection
couldn't be completed.
| Also, does anyone know where I can find documentation on what the error
| codes means such as 500, 421, 554, etc.
RFC821 contains these error codes. You can get a copy of the rfc from:

| Any suggestions or comments will be much appreciated.
| Thank you in advance.
