ignoring out-of-order original recipient, Postfix and Linux

[Philip Ludlam]

Hey All,

I want to flag up that I found my email going pear shaped with Postfix 
Qmgr reporting "ignoring out-of-order original recipient <username>" and 
then dumping the email.
This happened to every single email to me from 08:00 through to 23:00 
(ish) yesterday. At 23:00 I discovered what was going on and started 
troubleshooting it.

After finding no configuration change in MailScanner or Postfix that 
made a difference I went back through recent system upgrades; even 
downgrading to Postfix 2.2.5 didn't work.

It took me a while and googling brought up a few Postfix mailing list 
messages and comments that the Postfix guys don't like MailScanner or 
any other app messing around with their queue files ;-) .

But I did remember the discussion a few months back about how 
MailScanner handles locking files.

So, thinking that this was a file locking issue, I went looking for PERL 
upgrades and found a recent kernel upgrade from 2.4.32 to 2.4.33.4.

Booting back to 2.4.32 solved the problem and emails are now coming down 
fine.


So is anyone running Linux 2.4.33 and Postfix without this problem?


Phil L.
