Hi,
I'm starting to have regular occurrences of an issue where some email users are consuming huge amounts of bandwidth. Here are some grep'd example lines from /var/log/maillog:
Every time this user checks their email it's logging 18MB of bandwidth, yet it's not delivering any emails, just interrogating the headers. This user does have 150MB of emails in her imap/cur folder and has consumed over 12GB of bandwidth this month already according to Directadmin.
Another user I have been having problems with has certain emails (malformed SPAM type emails?) getting stuck in his account and consuming bandwidth on every POP3() check whilst the restof his emails download without issue.
Can anyone give me pointers on what may be causing these issues?
Thanks, Paul.
