Denis, Consider setting up Mailman, either yourself or if your ISP has it available. SpiritOne/Aracnet does and I've a couple of maillists set up there. The ISP provides upgrades and security so I don't have to futz with it. What might be directly related to your issue is a situation I recently resolved with my newsletter (approximately 600 recipients). I sent it using mailx in a simple script. Once a certain number of recipients of the same message was reached I started to get bounces with a 300 code. Investigating that problem taught me that because I must relay outgoing mail through my ISP's mail server I hit their limit. Above 300 different messages to different addresses per hour and/or 100 of the same message to different addresses per hout looks like spam and is throttled. Galen pointed me to the solution. In my local postfix installation I limit outgoing messages to one per 13 seconds. That allows me to send 276 messages per hour. I divided my newsletter address list into separate files, and send each one at approximately half-hour intervals. No more bounces. It might be that Google is throttling your maillings because the volume/time makes them appear as spam.
