BulkMail Issues on Linux Servers

New postby jponnusamy » Thu Aug 04, 2016 10:41 am

Dear All,

I am new to PostFix, I got mail from our ITS Team stating from Two Servers they are getting bulk mails (Around 15K) to unknown senders. So, they disabled PostFix on these two server until find the root-cause,
I checked our code and disabled the code which are using JavaMail, but still I could see the errors in the log. Even mail log getting generated after stop the Application Servers.
Kindly please help me to resolve this issue.

Code: Select all
