601 Error, cannot send any emails
Problem reported by elance - December 8, 2015 at 11:46 AM
Submitted
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.
 
Sample failure message:
 
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:

There were no changes at all to the server.  This just started yesterday.

Still having this issue today.  Cannot send any emails to any address.  Tried restarting the email service.  Not sure what else to do but this is now affecting business.  Anyone have any troubleshooting ideas?

Well a good old fashioned server reboot seemed to solve the problem, although without explanation.

It is Windows, you know. A couple of weeks ago, the Smartermail service on a client's mail server just stopped; it was possibly in response to restarting an adjacent server that the network was also using for a local forwarding name server, but still, no verified reason - happens just about never, so I didn't look too closely. Luckily I was on-site, and it was brought to my attention very quickly. The server, including SM and Windows software, is generally quite reliable.

In my experience, 601 can occur when DNS lookups aren't working.
