Hello,
I'm using mailman 2.x with postfix with much trouble. Recently I started seeing a lot of errors like this:
delivery to xxx failed with code 452: 4.5.3 Error: too many recipients
I do have both mailman and postfix configured for max recipients of 10, so I don't understand why there would still be complaints.
Any suggestions on how else I can further debug this?
thanks
Ricardo

Do you mean you have set SMTP_MAX_RCPTS = 10 in mm_cfg.py. That would limit the maximum number of recipients in one SMTP transaction from Mailman to Postfix to 10. Other settings such as VERP_DELIVERY_INTERVAL could reduce that further, but it would never be more.
This doesn't seem to be a Mailman issue, but if I were trying to diagnose it, I'd look at all the Postfix log entries for such a message, and I'd also determine if this is a single domain returning this error or multiple different domains and since it is a 4xx error it should be retried, and what happens on retry?
