[Mailman-Users] messages fail to @yahoo @aol @outlook

[Jayson Smith]

Hi,

The problem I'm familiar with is messages *from* AOL/Hotmail/Yahoo/etc. 
being rejected by other Email providers. I haven't done it in years so 
I'm not sure where it is, but there's an option in the list config to 
munge the From: lines of messages where Mailman detects this will be an 
issue.

If that's not the problem, my only advice would be to check to see if 
your IP is on any spam blacklists, insure SPF and DKIM are set up for 
better message authentication, insure your IP has proper reverse DNS, etc.

Hope this helps,

Jayson
