How do I receive mail as root via dovecot using "plain" authentication?

http://serverfault.com – I yum installed dovecot, then started the server. Here is what happens when I connect via telnet: xinaji:~ xinaji$ telnet cerulean-OW1.uni.cx 110 Trying Connected to cerulean-ow1.uni.cx. Escape character is '^]'. +OK Dovecot ready. USER [email protected] +OK PASS mypassword -ERR Authentication failed. Pretty straightforward, but mypassword really is the password for root (that is, root the system user in /etc/passwd). So what is dovecot basing the password on? How do I get it to base the password on the system user's password? (HowTos)
