CentOS - Mar 2008 - dovecot & bandwidth limit

Everyone,

I am having some bandwidth problems caused by large e-mail files with
dovecot.  From my research into dovecot it appears that there is no way
to limit the use of bandwidth during POP3 deliveries.  

What recommendations might some of you have for a different POP3 server
that can limit its own bandwidth use.


Thanks,

Greg Ennis

Maybe setup a firewall that limits bandwidth per session based on a
percentage of available bandwidth with a burst rate.

There are how-tos out on the net on this.

Ross,

Thanks for taking the time to answer.  I am familiar with the technique
in fact I use a burst rate for port 22 connections.  If I can not find a
POP3 server to do to limit bandwidth, I'll use iptables.

Thanks again,

Greg
