[extropy-chat] Clamping down email server

I've been sending and receiving my email through my hosted FreeBSD 
server for years, fairly smoothly. Of late I've been getting 
thousands of messages a day purportedly from other mail servers, 
rejecting email attributed to my domain, viz., that uses a random 
address like jkkqrlaz at unreasonable.com.

Meanwhile, there are signs that some email I've originated is not 
getting to its destination, suggesting that it's being blocked along the way.

I've checked a couple of blacklist sites, and not found my domain or 
its IP address listed, and confirmed that sendmail is using POP Auth.

Could someone point me to a straight-forward procedure for clamping 
down my email server, seeing if it's on any blacklists, and restoring 
its good name?

I plan to switch soon to a new web host, where I figured I'd rely on 
postfix, but I need email fully functional right away.
