I was rooting around soda for some other reason and stumbled upon the mail logs (!) for soda. I just sent myself some mail to generate a sample entry. It's got complete traffic analysis data, complete with to/from pairs, time of day, and message size.

If you need a place to start looking, the mail log on soda was in the same directory as the syslog messages. I would also recommend that this information on mail logging by the system be put in Karl's remailer list. Eric
