Hi,
I need to configure a smart host for Exchange Online (Office 365), i.e.,
all email sent with Exchange Online should be relayed through an
external Postfix server (smarthost). O365 allows a smarthost to be
configured. Unfortunately you can only configure the hostname (or IP) of
the smarthost bu
Hi everyone,
i'm trying to alter the relay host for bounced messages with the
following master.cf entries:
bounceunix - - - - 0 bounce
-o relayhost=my.smtp.host
defer unix - - - - 0 bounce
-o relayhost=my.smtp.host

What did the pickup daemon log *before* this? Error messages
from the pickup daemon are rare.

Postfix 2.10.1
I have spent some time today searching postfix documentation for
enabling xforward in smtpd. I am not seeing it in the response to the
EHLO when I telnet into localhost 25. I cannot find any reference to
what to put in master.cf (or main.cf) to do this.

More of an experiment since its easy to replace the tickets.
I wanted to try something a wee bit more secure. There’s actually a downstream
reason for this…
But of course, I’m still at a loss as to why the initial rDNS handshake as well

Don't be a crypto fashionista. Generate a 2048-bit key and obtain and
deploy a corresponding 2048-bit certificate.

Look for the mesage in the maildrop queue.
postqueue -p
postcat -q the-queue-id
pickup daemons should not crash.

Sorry this hit my junkmail folder…
The fix to this was to turn off SELinux.
Everytime the smtpd daemon tried to read the cert, it would get denied.
Once I turned off SELinux… it was happy.
(Of course the cert is 8192 which may be a bit excessive over 2048)

You've provided no information on where the performance bottleneck lies.
What are the averages of the delays=a/b/c/d log values?
Thanks to Viktor for the reminder to "proof the performance bottleneck"
Today I send 5k messages and /measure/ the times.

Hi Guys
One of my SMTP servers became unavailable yesterday. I'm not sure if it
is directly related to Postfix but I am seeing the following out of my
syslog log (especially interested in the kernel: segfaults):-

/usr/lib/postfi
