Hi
For no apparent reason in the middle of the morning, all incoming e-mail to my company stopped. Sending a test meassage from my internet m,ail account I got a bounce back with 550 550 5.7.1 Unable to relay for geoff@exsurrey.com.
 
Forgive the detail following but I am new to managing Exchange servers and this is giving me a real headache! Various info gained from Internet searching all seem to relate to issues following srver reconfiguration. No changes have been made to our exchange server which has been operating happily for 6 months or so.
 
The problem is affecting all mail recipients.
Our e-mail is effectively down and I am desparate for some guidance!
 
 
I have rebooted the Exchange server with no effect.
 
The headers of the bounced message are:

OK All,
just in case someone else can benefit...
Turns out this was caused by a software engineer installing a port redirection for some new software deleting the port 25 redirection on our router :(
