Can anyone webhosts that use majordomo and that what they're doing?

[StacyAnn <stacyann1 @ net-marks . com>]

I recently took over 2 mailing lists [ the previous owner used esosoft - 
but they had billing problems]

My hosting company can't seem to handle the lists.  The lists have approx 
1000 users and 200 posts a day.

If you know a webhosting company that "knows" their Majordomo please email 
me privately .

Thank You
