IPv6 support for Mail/Postfix

After adding and enable an IPv6 address, how do I get xserver to start listening for ipv6 mail requests?

Looking at the main.cf I see:
inet_interfaces = all

But running netstat -an | grep 25 I don't see tcp6?

tcp4 0 0 *.25 . LISTEN

Just to check sanity, I can ping it via ping6.
And ssh is listening:
tcp4 0 0 *.22 . LISTEN
tcp6 0 0 *.22 . LISTEN

Is there something more missing?

Mac OS X (10.6.6)

You need to edit /etc/dovecot/dovecot.conf

You need to change your listen command to the following:

listen = *, [::]

Please note that the above command needs to have brackets around the colons - for some reason the forum software is deleting them.

Also, I found that not only did you have to change the listen command at the top of the configuration file but also change the listen command to the above within the IMAP and POP3 (I only edited the IMAP since I don't use POP3) specific configurations that are found further down in the file.

Thank you.

I added:
listen = *, [::]

And now I see:

tcp6 0 0 *.993 . LISTEN
tcp4 0 0 *.993 . LISTEN

But what about fixing postfix, ie port 25?

In main.cf, have you set:

inet_protocols = all

?

So you should see these lines in main.cf:

inet_interfaces = all
inet_protocols = all
