Receiving lots of Mail Delivery Subsystem
Posted: Wed Apr 13, 2016 9:20 am
Hello all, I am new here, this is my first post after trying to find a similar case with no avail.
My issue is I have been using vesta cp for more than a year now, I have been able to sort most of issues that have happened in the past but lately I have some of my users in office are receiving about 100 Mail delivery notifications a day! upon checking the logs for exim at /var/log/exim/main.log I see there email accounts that are not even in the list of my domains such as these:
I have also tried but I get no such file or malformed message id feedback, and that I have done with lots of IDs without success hoping I may identify the script which is sending these mails which in turn fails and return a mail delivery notifications
Please anyone with idea to assist?, please!
