Hi Guys,

For some reason, in the last half an hour I keep getting this message come up when trying to send external emails...

-----------------------------------------------------------
Attention: Non-Delivery Report
-----------------------------------------------------------

This report is generated by the email server at:

xxx.co.uk

The message with subject:

"Disconnection Results for A/C :170xxxxxx"

and attached to this report was not delivered to
the following recipients:

Address: [email protected]
Reason: Verification failed for <[email protected]> (550)
--------------

Although when re-sending, they *seem* to go through the second time... im really lost to where to even start and would appreciate any help/guidance.

Cheers

Does this help?

 

I did see that when I searched, and kind of disregarded it due to the fact this exact setup has been working perfectly fine since I started here... We have made no changes to any hostnames etc..?

 

Anybody mess with any of your DNS records?

 

Only people with access to servers etc is me and the other guy in IT, who's off sick. This is whats strange, nothing has been altered at all. I think the first step in the morning will be a reboot and see if it helps...

 

Right, I woke up this morning ready to tackle this problem, got into the office and monitored it for an hour or so, and... nothing. Its no longer occuring, all outgoing emails are fine. Its now 12.36 and still, nothing.

Although im glad the problem is not longer happening, but annoying not to know what was actually happening and why.....
