I have a quick question.. Hopefully quick. I have been scouring the forums here and tried several things with no luck.. here goes my problem...
I have setup virtualmin on a brand new install of Centos 6.3 64, using install.sh...
My main hostname is yoyodyne.mydomain.com... as verifiedby typing hostname at shell...
In the post install, I have specified NS1.MYDOMAIN.COM - which failed though the entries are in the registrar... At any rate, I choose to go past this...
In Virtualmin, I have setup a virtual server of MYDOMAIN.COM, and added the support for email, website, etc.. The usual stuff that is pre-checked.
Now.. None of my email will send or receive outside the box.. I can send from firstname.lastname@example.org email to itself.. But to outside emails it fails with a 550 saying "550-No Such User Here 550 Sender verify failed (in reply to RCPT TO command)"
What can I do to resolve this? Currently I have spent sooo many hours over all to get to this point (BIND was a huge mountain of learning, which ended with the install.sh seemingly getting a working system going for the first time)...
