I can second that... most ISPs tend to block all SMTP servers except their  
own on port 25. GMail and some other services I am sure offer SMTP on port  
587. I use GMail's SMTP port on my N800 and have never had an issue  
sending mail with WiFi (besides the overly-protective county run networks  
at county buildings here that for the public block all ports besides port  
80... can't even access SSL there!).
