yeah, i ended up using dada mail, and i didn't really see any problems with the bulk mailings to specific providers- on the other hand, maybe it's the way i'm set up, but i'll tell you this much- i don't know if it's dada or tch, but my mailings don't always work. seems like batches just don't go, randomly, without reason. i get reporting on the batches, and i can't account for it. given the response i've seen about mailing lists here, i essentially shrugged and gave up- if it sends, it sends-- if not, well at least they can go to the website for news.
