Subject: Net::SMTP and Unknown User

Hi,

Situation: I've got a program that automatically sends out emails to
large numbers of people in certain situations.

Problem: Sometimes people leave the company and their managers aren't
always good about updating things. Since Net::SMTP#send_message seems
to be an "all or nothing" method (i.e. either an email is sent to
everyone or no email is sent to anyone), I'm not sure what to do about
this situation.

Things I'd like to avoid if possible:

LDAP: I'd rather not do an ldap lookup on every email address every
time an email is sent out. It's slow, and seems like there ought to be
an easier solution.

Manual Parsing: I _could_ parse the offending email out of the error
message, delete it from the array of email addresses and retry. But
that feels clunky and is probably error prone.

Suggestions?

Thanks,

Dan
