Ubuntu Server 13.10 | Postfix 2.10.2 | Cyrus 2.4.16

[Andrey ‪]

I tried again method of Dan, but with some workarounds:

rm -rf /var/run/saslauthd
ln -s /var/spool/postfix/var/run/saslauthd /var/run/saslauthd
chgrp mail /etc/sasldb2

Now I have in my configs (only sasl and virtdom related):

/etc/default/saslauth

But still, I cannot login from Windows live mail with username 
info at domain.tld. The unix user andrey can login, auto create mailboxes and 
special folders.
