Dovecot/Sendmail problem
 
I installed Dovecot on my fedora core 6 system as a POP server. My goal is to be able to receive emails @mydomain.com. Right now if I send an email to user@mydomain.com the email bounces right back with the following information:

Your message cannot be delivered to the following recipients:

Recipient address: user@mydomain.com
Reason: Remote SMTP server has rejected address
Diagnostic code: smtp;550 User unknown
Remote system: dns;mx1.mailhop.org (TCP|10.23.32.29|51983|63.208.196.176|25) (mxin2.mailhop.org ESMTP Exim 4.63 Sat, 10 Mar 2007 21:34:19 -0500)

As you can see I'm using dyndns's relay service because my isp blocks port 25. So I have redirected to port 587 by making the changes in sendmail.mc to accept incomming connections on that port. I also openned port 587 on my router's firewall.

The user exists as a regular user on my linux system so I don't know why the message isn't being received. Any help would be appreciated.

Thanks

This may be a stupid question, but did you actually start the dovecot process (service dovecot start)? If it isn't running, you will get a response like that. If you want to check, at the command prompt type," ps -ef | grep dovecot". You should see some processes running other than the request you just asked for. if not, then type the start command as above. Try that and repost.

found solution
 
I found my problem, I had to remove authentication for my server. By replacing a lowercase "a" by uppercase A in sendmail.mc. Everything works great now.

which "a" did you change? I'm having the same issue and that seems to be the solution to my problem.
