My server was working fine until yesterday .
It mow will not send email s to the internet but will send internally.
The SMTP connector was sent to rouet directly to the internet via DNS and was working fine ..
Now when i check the queue weird things are there ..
Heaps of what looks like spam generated by the server to be sent to 100's of random addresses by a email account called firstname.lastname@example.org, which ismt a user account , they all are in the queue state and retry to send amongst legitimate emails but fail to send.. i try to force them to connect to no avail.
Im currently running a virus check with eset NOD32 antivirus ..nothing so far
Has my exchange SMTP been overtaken by a virus? or is a virus running a SMTP engine thats preventing port 25 from being used ..
Can anyone tell me how i can diagnose another process using port 25 or suggest whats going on ??
PLease help im screwed without internet email , i can attache a screeny of the queue if anybody wantd to have a look see...
