It seems to have
the same problem as Net::SMTPthis problem though: there's no useful return codes. There's no way to distinguish between:
- - server timeout
- - bad/rejected sender
- - bad/unknown target
- - target user over quota
- - temporary server error
- - ...
not to mention the fact that all of the recipient-related errors can occur for each RCPT TO: line in your request, so
unless you get error codes for each of those you don't know which of your recipients will get the mail and which ones won't.
