Bandwidth throttling for SMTP port?

[Scott Galambos]

Is it possible to throttle bandwidth for a given port? I don't want to limit or stop bandwidth, just slow all SMTP traffic down. WHM 62.0 (build 21).

Hello Scott,

This functionality isn't directly offered in cPanel & WHM, but you may find the following URL helpful if you'd like to implement it using a custom iptables ruleset:

IPTABLES - Limit rate of a specific incoming IP

I also encourage you to vote and add feedback to the following feature request if you'd like to see this functionality added to cPanel & WHM:

Bandwidth Speed Limit

Thank you.
