Gmail will also display that error message when you attempt to forward
them spam as well. It will eventually let the messages pass after a
short delay.
You can increase your: smtp_mx_session_limit. The default is 2, by
increasing it to 5 it will try more gmail SMTP servers.
smtp_mx_session_limit=5
Also, I increased my flush delay from 1000 to 1800 so it runs every 30
minutes. Gmail doesn't complain as often with a longer retry it seems.
flush unix n - n 1800? 0 flush

I use virtual aliasing to forward inbound mail for family members

aol, too).
1) What's the best way to forward family members' incoming mail to
Gmail (and other mailers)?
2) My Postscreen and main.cf <http://main.cf> sender restrictions
are rejecting a fair amount of inbound spam, but apparently not
enough to keep Gmail happy.
3) Should I consider setting up SpamAssassin with some very low
thresholds to pick up the obvious stuff?
I have a not-dissimilar setup and I have various fixes to minimise
Gmail's upset. But I guess the first q is whether you need to be
worried about the 'rate-limited' messages. If you have a low volume of
incoming emails anyway a bit of rate-limiting is hardly likely to be a
problem.
