Hello, when trying to send a email from outside my server, to a account on my server, i get the below error. I also get it when trying to send to a email address on my server, from the server itself. I can send from the server out to say, yahoo.com email address just fine, just nothing into the server.

Requested action not taken: mailbox unavailable
Server replied: 550 "Unknown User"


I searched, did the "fix's" that were recommended for similiar problems, but nothign worked.

Any ideas besides reinstalling everything from scrach? I've never had this problem before. Current server is a VPS, with all the accounts transfered from another vps.



Not sure what else to do If you have suggestions, please let me know.

Thanks
Chris

Just found this in my dns entry

I'm not posting the domain, but following after the normal enteries are:

TXT "v=spf1 a mx ip4:69.73.179.227 ?all"


That is the old VPS server that I was on. When I restored the domains, I opted to have server change to the new ip's instead of keeping the old ones, but that is still shown.

On a test domain I just made, it shows TXT "v=spf1 a mx ip4:195.210.38.187 ?all" instead
Do I have to go through each individual domain and change it to TXT "v=spf1 a mx ip4:195.210.38.187 ?all" ?

Thanks MUch

Try a manual debug session.

Lookup how to use exim -bh and run a complete session, from your server shell, and see where the user is failing and why.
