Can't send email from droplet to to some servers,others are OK
I’m using postfix and cyrus which I set up as directed with mixed results. Yahoo and Gmail handle my emails well. Hotmail put it in the spam folder but doesn’t after being notified it’s not span. I tested by reading maillog after an attempt to send mail from DOserver to my roadrunner email account and observing maillog.
Here is the maillog entry:
Jan 2 06:10:55 Hanksite postfix/smtp: 49C48609ED: email@example.com,
delays=0.02/0.01/15/0, dsn=4.5.4, status=deferred
refused to talk to me: 554 5.5.4 Relaying denied.
IP name lookup failed for myIPaddress)
It looks like they can’t get through my smtp port. Why don’t the other major servers have the problems ? How can I fix this?
