dovecot - Oct 2014 - bandwidth shaping

Hey all, sorry if this has been asked before, but I haven?t really found a good
solution.  I have a mac at home and randomly, maybe once a week or once a month,
Mail.app will go crazy and use as much bandwidth as I have to pull down mail. 
I?m not home so I can?t tell what it?s done or why, and sometimes it stops after
an hour, sometimes it goes all night, leaving me with a potentially big
bandwidth bill for my colo?d server which hosts my mail (dovecot 1.2.9, postfix
2.7.0 on Ubuntu LTS 10.04).

I?m wondering if there?s a way to restrict bandwidth that?s the ?accepted? and
proper way with dovecot?  There isn?t anything (AFAICT) built into dovecot, and
the alternative seems to be setting up bandwidth shaping with ?ip?, but that is
a pretty horrible nest of ugliness.

Is there a fairly simple setup to set it so imap/pop traffic can only ever use
1mb/s (or some arbitrary number)?  I?m not looking for a one liner, but each
time this happens I say ?I?m going to figure this out and fix this?, then get
lost in ip and shaping queues and give up in frustration until the next time it
happens, when I say ?I?m *really* going to figure this out this time??.

Anyone have any pointers? 

TIA

Alan

not really, you should do more analyse what happens exactly
meanwhile switch to thunderbird...
Ubuntu LTS 10.04 runs out of support go update to trusty which will have
more recent software versions dovecot and postfix
