default main.cf.tls causes syslog warnings

[Emil Sit]

Binary package hint: postfix

The default postfix conf in Debian git and also in postfix_2.5.1-1ubuntu1.diff.gz includes the lines:

  smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
  smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache

Since Postfix 2.5, this causes the following errors in syslog:

Mar 26 23:08:13 yyy postfix/tlsmgr[8508]: warning: request to update table btree:/var/spool/postfix/smtpd_scache in non-postfix directory /var/spool/postfix
Mar 26 23:08:13 yyy postfix/tlsmgr[8508]: warning: redirecting the request to postfix-owned data_directory /var/lib/postfix
Mar 26 23:08:13 yyy postfix/tlsmgr[8508]: warning: request to update table btree:/var/spool/postfix/smtp_scache in non-postfix directory /var/spool/postfix
Mar 26 23:08:13 yyy postfix/tlsmgr[8508]: warning: redirecting the request to postfix-owned data_directory /var/lib/postfix

This is an incompatibility noted at http://www.postfix.org/TLS_README.html#client_tls_cache (and correspondingly for server side cache) and http://high5.net/mirrors/postfix-release/official/postfix-2.5.1.RELEASE_NOTES

Simply patching s/queue_directory/data_directory should fix this bug.

I'm running Hardy with:
$ apt-cache policy postfix
postfix:
  Installed: 2.5.1-1ubuntu1
  Candidate: 2.5.1-1ubuntu1
  Version table:
 *** 2.5.1-1ubuntu1 0
        500 http://us.archive.ubuntu.com hardy/main Packages
        100 /var/lib/dpkg/status

Attached is a patch against the git upstream.

I should note that I haven't actually tested that the patch works when built into a package, etc. But making those changes in my /etc/postfix/main.cf got rid of the error message.

[Scott Kitterman (kitterman)]

Wasn't there also a patch that made /var/spool/postfix/ a postfix owned data directory?

[Emil Sit (emilsit)]

That'd work too, I suppose. I didn't see any bug that looked like this in launchpad but I didn't check the Debian BTS. A 30s glance at that now also doesn't reveal anything obvious. I think changing the default location is cleaner and is what postfix is doing anyway.

[Scott Kitterman (kitterman)]

Debian and Ubuntu postfix maintainer are the same person. I've suggested he look into fixing this.

[LaMont Jones (lamont)]

Lacking a /var/cache/postfix directory, I suppose this belongs in /var/lib/postfix. It certainly doesn't belong in /var/spool/postfix.

[LaMont Jones (lamont)]

Fixed in 2.5.1-2. Please sync from debian.
