Postfix: Upgrading to Snow Leopard, User+Group Changed

I'm a bit late to upgrade, so everybody else probably already knows
 

My MacBook has a local postfix setup with a smarthost that I use to send out mails written in mutt. When upgrading from Tiger 10.4 to Snow Leopard / Mac OS X 10.6 (a long time after that came out, skipped 10.5 entirely), the setup failed with the error message:

postfix/sendmail[13601]: fatal: file /etc/postfix/main.cf:
parameter mail_owner: user postfix has same user ID as _postfix

So I went and edited main.cf to fix mail_owner to be _postfix. After that I got:

postfix: fatal: file /etc/postfix/main.cf: parameter setgid_group:
group postdrop has same group ID as _postdrop

So I had to change also for setgid_group the group postdrop to be _postdrop.

With those changes, my smarthost setup worked again without problems.

So you are telling me you have upgraded to Snow Leopard when Lion is expected to be out this summer?

I'm not only a lazy slacker, I'm also damn conservative in
software choices. If it wasn't for some specific reason[1],
I would have stayed on 10.4 till the poor machine fell apart.

[1] VueScan runs much, much better in 64bit on 10.6. Really.
