The complete error is:
Sep 15 08:00:08 localhost postfix/smtp[25057]: 16AE21000D17: to=, relay=smtp.embarqmail.com[206.152.134.66]:587, delay=1.5, delays=0.95/0.43/0.1/0, dsn=4.3.4, status=deferred (host smtp.embarqmail.com[206.152.134.66] refused to talk to me:
I see this either when sending from my MUA or when postfix is sending out cronjob notifications to me. It doesn't happen every time a message is sent. This has been going on for maybe two weeks or so. The deferred messages eventually do go out but it may be minutes or hours before they do.
Anyone with ideas on why?
