I have 106.8 installed on a 15-inch MacBook Pro. When at home, I use cable for internet. I have Gmail (IMAP), AOL (IMAP), MacMail (IMAP) and an educational POP account. All sync and work well at home. I travel internationally several times per year. When I leave my home network and travel in US airports, there is no problem. In Europe and South America (currently in Italy), I cannot send or receive from any account. I am able to browse with no difficulty. What are the solutions for:
What the the overall problem to prevent this in the future. It seems to be common when changing networks in some US locations and all outside North America.

What is most likely happening here is that the networks you are connecting to are locked down to only allow HTTP(S) traffic. You will need to use the webmail interface (if available) for each email account while on these networks.

Is there any other method to verify that this is the actual cause of the problem before I give up? Next trip I wil use browser mail, but I don't have MobileMe for some accounts. I will have to copy 39 Outbox mails to a browser if there is no solution.

Open a command prompt and type:

telnet yourmailserver 25

Replace yourmailserver with the outgoing mailserver in your mail client. You should get an SMTP banner. If you get a blank command prompt or an error, you know they are blocking the port.

Unfortunately, I returned to a stable local network before I could test the troubleshooting. I will close the question and refer to it when I encounter it again.
