have the same issues with some wifi connections, but not all.

I use IMAP/SSL and SMTP for my email on all devices, and a few locations appear to have those ports blocked (pubs, cafes, etc). When asked, they all claim not to, but I suspect either they don't know, or their provider is blocking them. It all works fine on my own network at home.
It might be your own ISP blocking SMTP port 25 to prevent spamming. Some provide another port for those who wish to send email while off net. Mine uses 587.

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!).
I have noticed the public city network here, at libraries, community centres etc. block OpenVPN on UDP 1194 and also SSH on TCP 22. I haven't tried secure web sites though.
