Wow! It is clear that you have a level of knowledge that indicates you are savvy in the Linux environmet. Having said that, you have lost me. OK, not so much lost, rather, I only see so many avenues to persue. Compounded by the last post that does not detail what you were able to resolve.
It would be lovely if we could all speak in shorthand (shortspeak/shortwrite?) and have the receiver perfectly understand what is being transmitted.
From your first post:
I don't seem to be able to send or receive mail to my mail host.
There is much to say about this. In fact, there are many posts on this forum that may provide clues, if not, solutions to this problem. Please use the search button above.

From my ISP when I tried to SEND from my ISP POP3 mail account that functions, I got a return that stated: ....etc

From your second post:
Okay. Got that part taken care of
What? The 503 error?
however I'm having problems sending and receiving e-mail.

Consider this: Scalix delivers mail internally based on an O/R name. If a message is destined for an external internet address the message i.e. an internet address, the message is handed off to sendmail.
If you understand that, think of sendmail as your POP account. Your POP account needs to know the smtp server through which it needs to send through; as does sendmail. If your POP account needs authentication then so does sendmail. Does that help?
So many, many, many of the issues raised concerning Scalix revolve around DNS.
You must have an A record, a CNAME, and reverse DNS configured for the host that is acting as you Scalix server. If you are relying on /etc/hosts then there is much that must be configured manually.
Firstly is your /etc/hosts.
Secondly we need to know the contents of the uncommented portions of /var/opt/scalis/sys/smtpd.cfg. Please post what you see there (change the names to protect the innocent.)
The OMHOSTNAME in /opt/scalix/global/config/, must equal the fqdn of the scalix server.
There may be things in /etc/mail/sendmail.cf and /i/dont'/know/what that need to be configured.
Could you please get dns configured properly.
After DNS is configured properly and if this is, as I presume a new install, uninstall everthing and reinstall again.
If you continue to have issues please explain exactly what you perceive the problem and/or problems to be. If there is more than one problem, please post them seperately, unless of course you think they could be related, then post the questions one at a time.
To repeat, you've completely lost me. I don't mean to be rude. You are just asking a plethora of questions, all of which have many answers. If I may be so bold, please look at the install guide and the release notes.
If you use the search feature and get lucky on the responses I think you will find that many of your issues are DNS related. Scalix is very finicky about DNS configuration(s).
Best wishes,
