Further to my investigation, instead of mass subscribing 150 email addresses, I just only subscribed about 60 or so email addresses and the mail listing worked.

Does that mean there is some sort of "hard" cap on the mailman program? I am using 2.1.12cp3

Hi everyone!!

A problem I came up with is that when I was playing around with about 5 members on the list I was able to send out an email and the recipients were able to receive them too.

However, when I added extra emails via "mass subscription" (approximately 150 from an old emailing list) nothing would happen afterwards when I try to send off an email. Basically, I send off an email to the mailing list address but the recipients won't receive anything at all, not even the initial 5 addresses that were working previously.

The only thing that has changed is that I've initially had 5 members which had no problem but as soon as I added the 150 the recipients the problem started.

Any ideas?

Thanks!
