I run a mail server using a static IP, but for a while, GMail would
refuse any messages from my server, saying that it was a dynamic IP.
I've enabled SPF on my DNS server, and that seemed to fix the problem.
However, I'm curious to know how a server can know if an IP is static or
dynamic. How can you find out?
Thanks,

Also, I stopped using my server at home as a SMTP relay after I found
out that many sites (ISP's and companies), just drop messages
relayed via a dynamic IP address, as the one you get from Rogers. I
guess they assume that they are SPAM.
