Yahoo! At my homework - er, I mean - emails

So, I'm looking for musicians to start a band. I've carefully worded my ads to weed out people whose goals are different from mine. I really don't want to waste time on yet another project that'll never get out of the garage because the other members want to do all prog-rock radio (look, I like prog-rock too, but it doesn't fly in the bars).
Great.
It's worked.
I've had many fewer responses, but most of them I've gotten were the people I was looking for.
And I lost several of the best ones because of an e-mail screwup.
Apparently, anyone on Yahoo! I send e-mail to from my mail server has a greater than zero chance of never seeing the e-mail.
So, at least two of the people that I thought were great until they turned out to be flakes (never answering my e-mail to them) are probably not, in fact, flakes. Too late to fix it now with them, but fortunately I have a singer and a drummer who thought to call and ask me about the lack of e-mails.
This is the third time in ten years Yahoo! mail has caused me problems.
GRRRRRRRR!!!!!!!!!

You know, it's hard enough finding good people who aren't already in bands....
