If you are sending to multiple recipients in one transaction, they are grouped by TLD but not by sub-domain within TLD. You need to tell Mailman to send one recipient per transaction. You can set SMTP_MAX_RCPTS = 1 in mm_cfg.py, but if you're going to do that there is no downside to enabling VERP for better bounce recognition with the setting VERP_DELIVERY_INTERVAL = 1 That setting is sufficient to VERP all messages which ensures each SMTP transaction has only one recipient. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
