Hi, First of all, I need to know how can I find wich mail's account did this unusual IMAP's transfer. I can find this in one specific log for example? Second, there are possible this problem is one bug caused by WHM/Exim or not? Thanks

  I found the solution to find the bandwidth one mail account use in one day using this command line: cat /var/log/maillog | grep "account@domain.com" | grep "imap" | grep "Logged out" And I found the problem: one user was using some mail's accounts to transfer data with each other users instead of using one cloud drive such as google drive per example LOL.

  Hello @Ot"vio Serra, I'm glad to see you were able to determine the source of the usage. Thank you for sharing the outcome.

  A slightly better way to discover more bandwidth usage is this command: cat /var/log/maillog | grep "account@domain.com" | grep "bytes=" This will include results from other commands like a UID SEARCH. In my case just one of these accounted for a gigabyte of data.
