SMTP Server name while on Travel

Two questions regarding traveling with a Laptop:
#1 I was out of town for a few days and took my laptop.  Was at a place I have been before using their wi-fi with no problems.  I was able to read my emails fine with Outlook Express but was not able to send emails.  My outgoing mail (SMTP) is typically  This did not work.  I tried setting it to and it did not work.  I thought that I should be able to set it to any valid one, but neither of these worked.  I also tried changing the Outgoing Mail (SMTP) port and this did not help.  Typically 25 or 587 work.
#2 Also, another strange thing - I was not able to access any sites using either Firefox or Internet Explorer.  All other sites including yahoo were fine.  I thought maybe it was a virus but ran several scanning programs and nothing.
When I got home, both the email sending and accessing google worked fine.  Any ideas?

Your SMTP "problem" is normal.  You can usually only send using an ISPs SMTP server if you are connected to them. Were they to let just anyone send, this would be an "open relay", and they would be quickly swamped by spammers.  It is possible to use SMTP authentication, where a username & password can be used, but most ISPs don't support this. You could ask I guess.

Other than that, you may be able to use an SMTP server on the host system. Assuming the wireless connection was a home router connected to an ISP, the same SMTP server other machines in the house use should work.

Most ISPs also support some sort of web based email, you could possibly use that to send.  A free public mail service such at Gmail or Hotmail is another possibility.

I can't think of a good reason why Google site were down, it would require some toubleshooting on the site.
