The problem probably lies with the ISP having blocked port 25 for all but their own server. For example, at my home I use one ISP, that does not block port 25. I can mail out using whatever server I like. At my office, they use an ISP that *does* block that port. I can mail out using that ISP's mail server, or I can use a mail server that uses a different port for SMTP (like GMail). So as far as I can tell, your client's problem lies with the company he uses in Africa to connect to the internet. Next time he's there, have him try from his neighbor's connection ;-) HTH, Rick.
