[ale] mail server with dynamic IP?

[John]

*Google*
Google is an advertising company. I'm certain that many companies would 
prefer to not have their email go through a company of that type. For 
personal emails, this may be fine, for corporate emails, privacy matters.

*DHCP*
My connection is DHCP, but my IP hasn't changed in years.  Since 1998, 
I've had about 4 IPs total (I recall 3). The last change happened in 
2007. Still, having a 1-2 hour DNS refresh period (IP check every 5 min) 
is useful to limit any inaccessible server periods. Not all ISPs allow 
DHCP to last that long and will force IP changes daily.

Having a secondary MX record (plus server) in an alternate location is 
useful to prevent mail loss, even if you have a static IP and data 
center located server(s).
