I have a number of servers that run mailing lists. Since last April, a number of these accounts' bandwidth usage has dramatically increased. The mail volume on these servers has not change and yet accounts that use to generate 15 or 20 megabytes of bandwidth in a month are all of a sudden reporting bandwidth usage in the gigabytes. This doesn't seem correct.

Can anyone shed some light on this?

Thanks,
Brian

Hello :)

Please check the "Bandwidth" icon in cPanel for one of the accounts with increased usage. Does it indicate which specific service uses the most bandwidth?

Thank you.

Hi Michael,

It does. It is the smtp service that is showing the greatest use of bandwidth. It looks like SMTP is now being monitored for bw usage when in the past it wasn't. Is that something new that was introduced in the recent cPanel update?

Thanks.

Ok now SMTP traffic is no longer being monitored for bandwidth. cPanel is there a setting somewhere that turns bandwidth monitoring for SMTP traffic on/off on the server?

SMTP (sending email) bandwidth should be monitored by cPanel. This is not configurable. However, if you feel that services are using less bandwidth then actually reported, feel free to submit a ticket so we can take a closer look:

The following document also contains useful information:

Thank you.

Thanks Michael. I will have my datacenter take a look into this and see what is going on. SMTP traffic is definitely not being monitor. That I know for sure.
