Hello all,

I was wondering if anyone knew the size limit of a mailing list set up for Postfix was?

For example, in my alias file, I have an entry that looks like this:

blah: :include:/home/blah/mailing.list

In that mailing.list file, I have a lot of email addresses for our newsletter. However, when I got the new, updated list from one of my staff, there were 41,000 addresses and Postfix choked on it. I chunked it out to 5,000 and made multiple aliases, and it worked like a charm. So, does anyone know what the practical limit is?

Maybe I'm blind, or my search kung fu has become weak, but I haven't been able to find an answer.

Thanks in advance!

im not sure what the limit would be but using mailman would correct the issue. It is designed to feed postfix the messages. Works well as some people are running mailing lists with 100,000 or more users and multiple reply's a day.

Let me know if you need help installing or configuring mailman.

I am in the process of building a mailman server for a 30,000 member organization for a newsletter distribution.

I don't think there's a defined limit - I suspect you are simply consuming all available resources and then some.

I'd agree with mitchell that mailman would be a better solution if you can be bothered - it handles bounced messages and the like nicely, and all those other bits you'd rather not bother with.

Thanks guys! I didn't even give mailman a thought. I'll try that out. Thank you all very much for your help!
