550 Verification failed

Hello,

I'm using Asterisk PBX & have been battling setting up making the Asterisk
voicemail system email me when a new message arrives.

If, using Webmin, I log into a users email & manually alter the from line to
a valid address, then compose an email, it gets sent fine.

How do I change the from line permanently?

Do I have to change the server's domain? What's this I read about
masquerading?

Please accept my apologies if these are many-times asked questions.

The error message I get is below.

----- The following addresses had permanent fatal errors -----
home@MYDOMAIN.co.uk>

Sorted.

Changed the hostname to point to my actual IP address.
