Re: gmail problem

Hi,

first of all, check if your server is not sending bad email traffic (eg. compromised account misused for sending spam).
You can do it by listing the email queue and the listing the content of the email and look if it's not spam:

# list queue
mailq
# cat the selected email
postcat -q XXX

the XXX is the queue ID (something like 718ED18481F)

I administer quite large server and I have never hit gmail restrictions.

Re: gmail problem

ok It's ok now. Gmail blocked email, they stuck in postfix queue. The problem was with network, two active wan interfaces, some mails went out through a new one, with other IP, therefore mails apeared to be suspicious for gmail becouse of new IP.
