Hi all,

I'm looking to add some rate limiting to my postfix, but need to know how postfix's smtpd_recipient_limit interacts with mailman...

After thinking about this, I just don't really see any rational reason that normal users should be sending to 100 recipients at one time. If they need a list, they can ask me to set one up for them.

So, my understanding is that if I send an email to one of my lists, and it has 50 people who are at the same destination domain (ie 'example.com'), then mailman will generate a single message with 50 recipients to this one domain (and separate messages for other domains)

• is this correct?

If so, and if I reduce postfix's smtpd_recipient_limit to, say, 20, then I would also need to set SMTP_MAX_RCPTS to to 20 (or something lower maybe?), correct?

Thanks
