I have found that reading (and understanding) the Postfix documentation
is one of the best tools available, followed by trusting the defaults,
and reading the logs.
Are there any tools that would help in optimizing/tweaking the Postfix
configuration?

Hi,
I need to setup a mail server that will use delays based on domain names.
For now, I have a default setup with a transport_map with the domains I need to
send emails to. (Those domain are reached by our VPNs).

Hello,
I've upgraded to postfix 2.9.1,
put "enable_long_queue_ids = yes"

Queue Id seems to be longger and uses all letters in the log file...
Wait & see...
Thanks for all.

The problem is that the tool we have doesn't have access to the mail
files from the deferred queue.
It's main purpose is deferred queue management.
The emails we work with have special headers which are processed by that tool.
As you said that is not supported.
Anyway, the current backup plan is

The Queue ID is not reused before a message is removed from the queue.
Therefore there are no collisions.
If you need unique queue IDs, use Postfix 2.8 long queue IDs

I understand, we used to have version 2.0.x and there
we accomplished that by changing the default file permission in Postfix's code.
It looks like in 2.9.x the same approach does not work.
Thanks !

Yeah, I see that. The file permissions are hardcoded.
That is why I tried to change Postfix's code.
I tried changing those, but still somehow it makes the file non
readable for group members, but the read and write are left.
Hope to have some hint from a Postfix dev.
Thanks !

Hi,
I'm using Postfix 2.9.3 on a RedHat machine.
I'm trying to make Postfix mail files, from the spool/deferred dir,
readable by postfix group users.
By default they are readable only by the postfix user, 0700.
For instance:
ls -la /opt/postfix/spool/deferred/5/5C8EA46029F
