How to change queue id?

Hello everybody, I deliver mails to my Postfix through smtpd. Postfix then takes it and sends it out to the recipient. Now I'm trying to change the queue_id for each email in Postfix 2.9 source code so that it is equal to the Message-ID (it is unique, don't worry) that I set in the email heade

reject_unknown_sender_domain and DNS SERVFAIL result

I recently updated a Postfix system from 2.4 to 2.9 and I have found what I believe is a change in behavior for reject_unknown_sender_domain which is confusing. In the past, an effective means of dealing with some classes of persistent spammers was to tell the local DNS resolver (BIND 9) to "bl

AW: How to change queue id?

Thanks for all the insightful answers. So, I actually use the long_queue_ids options and I save the queue_ids to a database to later compare them to the queue_ids found in the mail log to parse and mark the bounces. The problem - and thus the source for my question - is that this always means a st

SOLVED! was Re: reject_unknown_sender_domain and DNS SERVFAIL result

Predictably, the cause of this odd behavior was in fact external to Postfix. The server has 3 DNS servers in resolv.conf: itself, another one sitting across the room, and a third far away which was added in the same disaster recovery event that precipitated the upgrade from 2.4.5 to 2.9.3 a f
