Re: Sendmail error "Deferred: Transport endpoint is not connected"

Are you getting this error on your own Sendmail server, or is it being

Yes, this is happening on my server. It's not a response code.

I'm guessing your MTA is
connecting to a remote MTA, and trying to send the message to the remote
MTA. The remote MTA is trying to run your message through some sort of
milter, but the milter is failing with that error message, so it sends
you back a "4xx x.x.x Transport endpoint is not connected." and your
log file therefore contains "Deferred: Transport endpoint is not connected"

FWIW: I've stopped & started all my milters and sendmail itself. No change.
