This started yesterday, the server has been working for years. I cannot send any emails to anyone, on any domain, not even Gmail, either from Outlook or from the Smartermail web interface. I get a delivery failure message eventually. I checked mxtoolbox and it didn't show any blacklist issues.
Nothing has changed in the last few days, so I can't figure out why this started suddenly.
Could not deliver message to the following recipient(s):
Failed Recipient: cbrown@gardenfreshcorp.com
Reason: Remote host said: 601 Attempted to send the message to the following ip's:
64.233.160.26, 173.194.219.26, 173.194.205.26, 74.125.141.26,
74.125.141.26
-- The header and top 20 lines of the message follows --
