Distribution specific hints

Gentoo

I cannot send/receive mail

Applies to:	Native Kolab2/Gentoo installation	Applies to:	Native Kolab2/Gentoo installation	Applies to:	All Kolab2/Gentoo versions
Found on:	Gentoo Linux	Found on:	Gentoo	Found on:	All Kolab2/Gentoo versions

Problem

You are unable to send and receive emails and see messages like fatal: open database xyz.db. No such file or directory.

Solution

After installing postfix you will need to initialize some of its basic databases. Make sure you ran the following commands:

/usr/bin/newaliases

postmap /etc/postfix/access
postmap /etc/postfix/canonical
postmap /etc/postfix/relocated

This should remove the warnings, postfix should start and you should be able to send an receive mail.
