Incorrect info being stored in AWL?

[jpotter]

I'm seeing something that doesn't make any sense to me. On a new install, with TxRep set to use MySQL for storage (via the AWL stuff), I'm getting rows inserted that are impossible.

Here's the data for an email address with someone I corresponded with. I have changed the domains for privacy.

Jpotter (me) and Jeremy are emailing each other. Jeremy is on a different system.
Matt Smithon emailed another user on our system; Matt is on a different system.

I've never emailed Matt; Matt has never emailed me.

Why are there rows in AWL that have Matt and Jeremy as a row? Neither Matt or Jeremy are on this system, they don't know each other at all, there's never been any email between them in any context.

Thanks!

select * from awl where email like '%foobar%' or username like '%foobar%';
