i use my own smtp server on my laptop and home pc it works well where ever you can pick up a wireless connection, the benefit is added privacy as all out going emails go straight to the persons pop3 inbox and no copy is therefore kept on your isp's smtp server.
i recommend the free version 2.6 of postcast smtp server - its a older version but does everything you could want as a user. its available here
http://www.postcastserver.com/download/release.aspx?p=3
you have the option after install to set your smtp server to work with your email programme (outlook express/thunderbird etc) or you can use postcast as a stand alone email client by clicking new and entering the address in manually, obviously you cant get your email through postcast as it a smtp email server.
in standalone mode you can put in the from field any email address you wish as its not authorised by your isp's smtp server -your server accepts all outgoing names you could wish for ! which if your 14yr old get hold of it he'll be sending all his mates emails from tom dick and harry in the from box.!!!
so yes this will do the job you want in hotels and cafes with a wifi connection and you can then send no problems. and get your imap incoming online.
if you need any help PM me
