Anyone have experience with bulk (~50k) mailings? I believe that the PN limits on their SMTP relays would make their use impractical. (Are business accounts treated the same as home retail?) Sending from your own server on an ADSL connection may be marked as un-favourable by many receiving servers if the IP is recognised as from an 'ADSL pool'. Of course there are commercial providers out there that specialise in bulk mailings, but you guessed it I've an interest from an organisation thats looking for something cheaper. Is there an issue in practice with an outgoing server at the customer premises for bulk mailings?
