MDdaemon mail problem '550'

I have a Mdaemon server with a registered domain name. and a local domain.

The registered domain name is used to exchange emails etc.. using the internet and the local domain s used for emails within our private wan.

we can send/receive emails with no problems

assume public domain = pd.com
we have users who retrieve their emails FROM MDAEMON and other (remote users) who retrieve their emails from the ISP

the problem is:
we can use the local domain to send/receive emails.

when we use the public domain to send emails to users (who use mdaemon), emails are sent successfully but when sending emails to remote users (users who use ISP) mdaemon respond with a '550' error.

the reason of this error is that mdaemon doesn't know the remote users. and  I don't want to create user accounts for these remote users cause in this case, the mdaemon will try to get their emails and the remote users won't be able to retrieve their emails via ISP (since mdaemon retrieved them and removed them from server).

I ibelieve there are 2 solutions to this problem: (which I don't know how to fix in both cases)
1- create accounts for remote users however instruct mdaemon not to retrieve their emails from the servers. then pass every email send from local users to ISP mail server via MDaemon
2- stop SPF and all type of SPamFilter that way mdaemon will consider the mail recipient unknown and will forward the emails to ISP mail server.

I believe one of these solutions should work. please advice on what/how to do it.

hi this is probably problem with relay configuration- non local user sending email to non local recipient.

There's a few ways:
1. Avoid mailserver - use port forwarding and forward pop3 and smtp ports to ISP provider and avoid the mailserver.
2. I didn't look at this mail server software, but there should be some account to logon for mail sending/retrieving. You should have one for domain and others for ISP directly sending/retrieving. You can just give a wrong pop3 server so the emails won't be retrieving (mail server could complain about this).
3. If you have option "Leave message on the server" for specified account - there's your solution (best way - you read their email, but they stay on server).

Forwarding (your solution 2) will confuse users since they will see a return route to your domain server (that is forwarded email).

Dragonmen, I read your comment and it won't work anyways I've found a solution:
the problem for mdaemon is that u cannot specify external users and let these other users send them mails. otherwise mdaemon will retrieve external users emails even if you instructed it to disable those external users account.

that was the big issue. letting local users send emails to external users (where external users access an ISP mail server not the mdaemon) in the same domain even without.

The solution is to:
1- not to create accounts for these external users
2- instruct Mdaemon to forward unknown mail to the ISP mail server
3- use header translation to forward emails from internal domain to external domain.
--------------------------------------------------------------------------------------------------

I've put these steps as reference for any person who needs help
