Steps to follow when server is moved under new IP

[Sruli Saurymper]

SPF and reverse DNS are not a must to get outgoing to work but many 
(maybe most?) will not accept emails from servers who do not have these 
configured. SPF record you setup in your DNS records reverse DNS you 
have to request from your ISP.
I don't know what to make of your current error, doesn't sound like its 
linked to SFP/DNS issue, is your SSL certificate IP or domain bound? 
now-days only domain bound certs are issued, does your ISP allow sending 
mail on port 25?
I cant help you much further on this, I am sure if you find more info in 
your log file and post someone will be able to help you.
