Postfix/SMTP error

[Cory]

Hi,

I am having trouble sending email from my mail server to .Mac accounts. This only affects .Mac accounts – I can send/receive mail to/from AOL, comcast.net, other businesses, etc. Here is the error from my SMTP log:

Feb 9 12:46:31 myserver postfix/smtp[6975]: A6BA723659: to=<[email protected]>, relay=smtp-mx.mac.com[17.250.248.49], delay=71875, status=deferred (host smtp-mx.mac.com[17.250.248.49] said: 451 4.1.8 Domain of sender address [email protected] does not resolve (in reply to MAIL FROM command))

I have done a DNSReport on my domain, MX record, A record etc. and all checks out fine. As I said, this error only happens when sending to .Mac email accounts (from any of the mail servers on my Xserve).

Any ideas? Thanks in advance,

Cory

Everyone,

This is fixed. It was an issue on Apple’s end that they recently fixed.

Thanks anyway,

Cory
