If you have widespread delivery problems, it's probably related to 
your IP and/or your reverse DNS hostname.

Make sure you have a static IP.

Make sure you have rDNS and it is not a "generic" DHCP-looking name.

Make sure your new IP has fcrdns.  This is a non-issue for web 
servers, but is vital for sending mail.

Make sure you publish SPF records listing your new IP.

It's also good to set up DKIM and maybe DMARC, but these are usually 
secondary concerns.


If you need more help, provide more information.
