Different handling of trailing dot in smtpd and cleanup in postfix,
Christopher Chan
With and without strict_rfc821_envelopes = yes, smtpd will accept mail
for recipient addresses with a trailing dot.
The problem is, smtpd will first feed the recipient addy through
trivial-rewrite, which will strip the trailing dot, and then go to
mail_addr_find whereas cleanup will go straight to mail_addr_find and it
will obviously not find the addy.
That means the mail is accepted by smtpd for the smtp session but
bounced later on as user unknown by cleanup.
