Even if you can make this work, it's still a bad idea, since the
outbound SMTP server will be blacklisted for sending to too many
invalid addresses. Because it ignores bounces, the mailing list will
never be updated to remove invalid recipients.
Spammers don't care.
I mean, come on, a custom SMTP that ignores errors? SPAMMER ALERT.
