dovecot-SASL for Postfix: EXTERNAL does not work.
Hello.
I am not subscribed and new here, so first of all i want to thank
you for dovecot. I personally do not use it in "production"
(yet), but it is my sole point of interaction for testing the
little MUA i maintain for quite some years. I also have used its
code for affirmation purposes. (Interesting that OAUTHBEARER
treats hostname and port as optional. I currently do

[wietse@porcupine.org: Re: syncronous directory operation for linux (ext2)]
There's a big thread about filesystems on postfix-users@postfix.org
Could you shed some light on that issue?

Using postfix in CentOS 6 to relay mails to First.Last@gmail.com
Hello fellow CentOS users,
I'm using:

static.103.78.9.176.clients.your-server.de
I own several domains and would like all
incoming mails addressing those domains
to be forwarded to my Gmail address.
So I have setup the MX-records for my

ext3 and chattr +S on postfix spools
Postfix <http://www.postfix.org> does a chattr +S on its spool directory
when it is installed on Linux.
This is what is written in the postfix startup script
--
#
# LINUX by default does not synchronously update directories -
# that's dangerous for mail.
#
if [ -f /usr/bin/chattr ]
then
CHATTR="/usr/bin/chattr +S"
else
CHATTR=echo
fi

Is this still required on ext3 ?

Postfix IPv6 defaults
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
According to Postfix mail list [1] Postfix RPM has IPv6 enabled by default.
Postfix source code distribution has IPv6 DISABLED by default for security
reasons.
It could be better to disable IPv6 because IPv6 autoconf could break security.

Fwd: Re: sasl parameters missing (in postfix)
In response to my request for postfix to support dovecot auth arguments I got
the forwarded reply.
If someone gets around to this before me I won't be offended.

Story is I deployed a webmail with certificate based authentication that
substitutes a global master password
(http://wiki.dovecot.org/Authentication/MasterUsers) when the certificate
matches. The webmail accesses
