RE: [Sheflug] Postfix setup

["Chris Johnson" <chris [at] xxxxxxxxxxxxx>]

I think I've sussed it!

Checking the var/log/mail.* files I found it was the "reject unauth
pipelining" which meant it was getting beyond the "access" file when
processing "smtpd_client_restrictions" (set to check_client_access
hash:/etc/postfix/access, reject_unauth-pipelining) and rejecting my mail.

My access file contained the following lines

192.168.100.0/24 OK
127.0.0.0/24 OK

I did a postmap and it didn't work

However adding the actual address of the workstation and server to the list
allowed each of them to them send mail.  I'm going to add the addresses for
the other workstations now as well.

Thanks for all your help.

One last thing:
Is it possible to see the queued outgoing mail?  (assuming its not sent
immediately)
and (OK it wasn't one last thing) how can I see a list of sent mail?  Does
anyone have a grep for one of the logs to see whats been sent to who and
when and whether it was successful?
and (really this is the last thing)
Would it be possible for a PC outside our IPCop firewalled network to
connect to our SMTP server and send mail by spoofing the address of one of
our own PCs (listed in teh access file?  I'm thinking that the Linux box
stays on overnight and as we're on ADSL there might be a bit of a security
risk.

(this should be via the postfix server)
