Postfix+dovecot+mysql ubuntu 10.04LTS

Hi,

I followed this guide to setup email server on my linode.

http://library.linode.com/email/postfix … 0.04-lucid">http://library.linode.com/email/postfix/dovecot-mysql-ubuntu-10.04-lucid

Did all the steps,

but after mailx contact@mydomain.com

I get error in the log

cat /var/log/mail.log:

Jan 11 12:51:35 li223-15 postfix/proxymap[22921]: warning: mysql query failed: Unknown column 'domain' in 'where clause'

Jan 11 12:51:35 li223-15 postfix/cleanup[23075]: warning: E864026547: virtualaliasmaps map lookup problem for contact@mydomain.com

Also,

cat /home/vmail/dovecot-deliver.log

cat: /home/vmail/dovecot-deliver.log: No such file or directory

Dont understand why these errors are showing up, may be missed any step while setting up postfix?

Any help/ideas?

Thanks,

Ajey
