One option would be to use your mta to rate limit it per destination domain. Then your mta can queue them up a few at a time. Other things you can do include make sure dns entries for your server are inplace and match. Spf records won't hurt. Also you might get the mta to do skim signing. Check reputation databases for your urls and up address.

Dear Mailman,

I use your program ver 2.1.11 cp3

The abridged version of my issue is this:

I have a subscriber list of over 2,000 people. When I send emails thru the mailman program, I'm never certain how many of those emails are actually successfully received by my list members, and how many simply never get there (due to spam filters & server restrictions).

I believe my issue is due to sending out so many emails at one time (the full 2000). Is there ANY WAY to send emails out to a specific group of members on my list? For example, mailman alphabetizes list members by name. Is it not possible for me to send email to members A-C then wait a few hours and send D-F then wait a few hrs more and send to members G-I etc?

Thank you so much for your assistance.

Steve
