Hi, I've just found the following in my postfix log:
> grep C5E7710205CD: /var/log/mail/current May 29 13:21:01 [postfix/pickup] C5E7710205CD: uid=65534 from=<sen...@mydomain.com> May 29 13:21:01 [postfix/cleanup] C5E7710205CD: message-id=<20090529112101.11351.11039.stra...@strato1> May 29 13:21:01 [postfix/qmgr] C5E7710205CD: from=<sen...@mydomain.com>, size=1355, nrcpt=1 (queue active) May 29 13:21:03 [postfix/smtp] C5E7710205CD: host f.mx.mail.yahoo.com[68.142.202.247] said: 451 Message temporarily deferred - [170] (in reply to end of DATA command) May 29 13:21:04 [postfix/smtp] C5E7710205CD: to=<recipi...@yahoo.de>, relay=f.mx.mail.yahoo.com[98.137.54.237]:25, delay=3.2, delays=0.29/0.01/1.7/1.2, dsn=2.0.0, status=sent (250 ok dirdel) May 29 13:21:04 [postfix/qmgr] C5E7710205CD: removed So the question: what has happened with that mail? I am confused about the line "451 Message temporarily deferred" immediately followed by "status=sent (250 ok)". Thanks and regards -stefan-
