Ah, for some reason all my searching didn't find those. I'll definitely look into them; thanks for pointing them out. If they are what they sound like, they could save me even more of the work than what I was looking for. (Though, I originally started out looking for a POP3 proxy, but I didn't turn one up, perhaps because CPAN doesn't know a proxy and a relay are the same, or perhaps because I didn't try looking for POP without the 3.)

update: Upon further inspection, the docs for these aren't as clear as I would like, but it *appears* to me as though they are a relay in the sense of receiving the message and passing it along to another account. One of the configuration options you have to set is for what process is the "mail program service"; the default is sendmail. So as near as I can determine, it wants to pass the message along to an MTA. That isn't at all what I want. Also, I examined the source of both modules and did not find any evidence of any network protocols being implemented, specifically not POP3.
