Bandwidth per email account

[User2012]

Hi all,

First post at these forums and I'm not very knowledgeable so apologies if my terminology is off

We have several accounts (domains) that we manage via cpanel.

One of them usually uses bandwidth of circa 700MB p/m but at some months it goes up to almost 5GB(!).

We can see the spike is happening at the emails of that domain but can't seem to find a way to drill down and find how much bandwidth each email used to find the offending accounts (who knows, it could be just 1-2 accounts causing this by sending spam or what not :-S ).

If there a way to do this?

Thank you!

Hello

While there are no native tools that will give you the bandwidth per email account, you can find unsorted bandwidth data for POP3 in the following file:

/var/log/maillog

I suggest searching the above file for the domain name in question to determine if a specific email user is displaying more activity than others. EX:

grep domain.com /var/log/maillog

The following thread includes some commands to grep /var/log/maillog for specific domain names and email accounts that you might find helpful:

Thank you.
