[Mailman-Users] Unable to send emails with mailman/postfix

[Adam Goldberg]

Check your firewall settings on the VM.  You may need to open up 25.

Hi Mark,

I've managed to forward port 25 to my VM. I am still not receiving messages
sent from my gmail address (on the list) to the mailing list.

The only other thing I've learned is that I can send mail to that same list
from the command line with 'mail -s', which leads me to believe postfix is
OK.


Thanks for all of your help,

Scott
