Hi, Did my postfix instance limit the number of recipients in the email that was sent ?
I was reading this at this link http://www.postfix.org/postconf.5.html default_extra_recipient_limit (default: 1000) The default value for the extra per-transport limit imposed on the number of in-memory recipients. This extra recipient space is reserved for the cases when the Postfix queue manager's scheduler preempts one message with another and suddenly needs some extra recipients slots for the chosen message in order to avoid performance degradation. Use transport_extra_recipient_limit<http://www.postfix.org/postconf.5.html#transport_extra_recipient_limit> to specify a transport-specific override, where transport is the master.cf<http://www.postfix.org/master.5.html> name of the message delivery transport. I have an email that was sent to [I don't know how many, still waiting for an answer] but logs show it went to 1000, and I see 3 more users that There is no record the email was sent. ALL the users were in the BCC field of the screen shot if that is important, and FROM and TO are same address. All I have so far is sender screen shot of outlook email. The account profile in Outlook is configured to send to my postfix server directly as seen in logs below.
