Port 25 and Static/Dynamic IP for Listserve SW

[Piper]

Port 25 is just the normal SMTP port isn't it?

So if I bcc this to 50 addresses of the ABC list in my Express mailbox it 
goes through Port 25 to all 50. And it uses a "dynamic ip" address.
No problem.

What is the problem if Evolution has a few more lines of code in it?
