just going through a couple of bounce messages that I have
received back from mailing lists, and came across a couple
of instances that cause me to question my responses.
The first is responding to a MAIL FROM with a
551 <address(_at_)domain(_dot_)com>... <ISPs NAME> ERROR 1 - call <#> for help.
The second is responding to a RCPT TO with a
554 Could not read response from aliasd.
Now, in both cases, I could not find (in 821 or 1123) the response
codes listed for the commands. Matter of fact, user not local for
MAIL FROM does not really make sense unless they have an anti-posting
filter or something out in place. Seeing as this is list traffic,
it really didnt make sense.
The second case I can almost see treating this as I do thr 550
to 553 responses, which indicate failures with the particular address,
but not sufficient to abort the connection (like mailbox full, etc.).
So, any input there on how these 500 level response should be
handled? current usage of any of these responses to these commands?
regards,
Jack
