Help in SF

I have an activist friend in SF (Mission Street Area) who needs help to set up email in a safe, good way. He can receive mail in, but has trouble sending out. He needs help in determining if there are bugs and also to create privacy. He doesn't have a lot of computer experience. Any suggestions/help would be greatly appreciated. If you email me and get no response until Thursday, it is because I'm out of the office and will not be able to read my mail until my return. Thanks, Mara (marw@fs-gate.uchicago.edu)
