Hi,

I followed this guide to setup email server on my linode.
http://library.linode.com/email/postfix ... 0.04-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: virtual_alias_maps 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

From the mysql error sounds like you missed this bit
