we need a bulk mailing software which can use yahoo / gmail / msn servers to send atleast 100k mails a day... it should automatically change IP and shift between servers so that the accounts are not blocked.
We should be able to place limits on number of emails to be sent by each account / time etc..
It should have the capability of sending unlimited mails (with attachments/ html) by adding unlimited number of free accounts... it should be automated as much as possible
we are looking for a ready solution so if you have developed something like this in past so that will be helpful.
Bids with reasonable price will be shortlisted
