Postfix says: "queue file write error"

[qrwe]

Hi,

As a postmaster for the mail server I administrate, I have gotten a message about an undeliverable mail in the mail queue. It says:


Out: 220 reciever.foo.com ESMTP Postfix
In: EHLO sender.bar.com
Out: 250-reciever.foo.com
Out: 250-PIPELINING
Out: 250-SIZE 20480000
Out: 250-VRFY
Out: 250-ETRN
Out: 250-STARTTLS
Out: 250-AUTH LOGIN PLAIN
Out: 250-AUTH=LOGIN PLAIN
Out: 250-ENHANCEDSTATUSCODES
Out: 250-8BITMIME
Out: 250 DSN
In: MAIL FROM:<user.one@foo.com> SIZE=12804
Out: 250 2.1.0 Ok
In: RCPT TO:<user.two@bar.com> ORCPT=rfc822;user.two@bar.com
NOTIFY=SUCCESS,FAILURE,DELAY
Out: 250 2.1.5 Ok
In: DATA
Out: 354 End data with <CR><LF>.<CR><LF>
Out: 451 4.3.0 Error: queue file write error
In: QUIT
Out: 221 2.0.0 Bye


I can't figure out what's wrong. Has anyone seen this before?
Thanks for any help.

You really need to look at the Postfix logs rather than the SMTP transcript. Post the relevent section of /var/log/mail.log as it may hold some clues about exactly which queue is not being written to. Do you have any virus scanning or other service that gets piped messages?
