August 23, 201015 yr Google's rate limiters are fairly conservative and have a very low false-positive rate even for busy peers. If connections from your IP address get bounced with a bulk policy warning, you should urgently review if your machine has been rooted recently and is actually sending out spam. If you can rule that out and are sending bulk e-mail to googlemail, you might wanna put a rate limit in to not annoy their mail servers.

I suppose the problem was originally that one user had a catch-all --> forward gmail. This was switched off more than a month ago. Ever since the logfiles (Logwatch : Sent via SMTP ) show max 1 - 2 mails send out to @gmail.com (that bounce anyway). I have to assume that Logwatch is reporting all outgoing emails from the server, or do I miss something here ? How would I put a rate limit in ?
