This is my first post at gethighforums.

I was wondering if you can point me to a mailing list software that can handle multiple daily lists each with hundreds of thousands of emails. We are also looking for a solution that can handle our opt in (ala postmasterdirect) lists.

Would prefer solution to be PHP based and that would retrieve addresses and message content from a mysql table.

I also am looking for a dula format solution: text/html.

And anyone knows how quickly can 100,000 emails be sent (assuming each is 3k) on a dedicated server Pentium 700 256 MBs of RAM?

We have been using Majordomo but I think we need to move forward with a script that can handle large lists better.

Thanks a bunch

Frank

I have been administering a site which despatches about 250,000 mails every week. It takes about 50 hours average. The only downside is,if the network traffic is hectic, sendmail tends to build up a huge queue in the folder - mqueue, taking up a lot of harddisk space. A well-configured sendmail application,running in Linux, can easily take this extra load without a murmur.

Thank you so much for your reply. We are actually seeking a solution that delivers 500,000 emails per day. 50 hours to send 250,000 is not obviously a viable option.

We are now using majordomo and that we find is able to send that amount in 20 hours. We want to go to less than 5 hours delivery time, meaning we want a solution that delivers 100,000 emails per hour.

Sending 100,000 emails per hour translates to :500 MB per hour (assuming an average mail of 5 k size) or 12 GB of bandwidth everyday.In other words, you need a minimum throughput of 1.0 Mbps to achieve this task. The server, I referred to above hosts a busy site delivering dynamic contents,in addition to sending these mails. Unless you dedicate a server exclusively to this mailing application, it will push the server to its limit.

We are not talking spam here. We have around 12 optin lists each with hundreds of thousands of users.

And FYI, solutions that deliver much more than 100,000 emails (500,000-700,000) per hour already exist but are very expensive:

Actually a general list of few hundred thousands people can be at best called moderate in size.
