so , i think the root cause relate to the if mailman does support spoofing sender or not ,

but from my another instance mailman server , the answer should be YES, cause this instance mailman server can accept mail sent from [email protected] to [email protected]

to Barry

i issue mail command on a Centos 6.5 which the mail version is mailx-12.4-8.el6_6.x86_64

and ,i did a further test last night ,

mailman did not accept those emails set their From address as the maillist address.

which means , for example , if my maillist address is [email protected]
then mailman server will not accept those emails sent from [email protected] to [email protected]

and if [email protected] is a aliase of [email protected]

mailman server can accept those emails sent from [email protected] to [email protected]

even aliase.com and mailman.com are resolved to a same IP address.

i think is related to the sender address

as i use -r to speacified a maillist address as the sender address and
send this mail to this maillist , Mailman will report the issue , which
mean while , if the from address is differen to recipient address,
mailman will accept it.

I am really trying to help you, but it is difficult when you don't
answer my questions.

Please see the post at
<https://mail.python.org/pipermail/mailman-users/2015-December/080249.html>
and answer the questions in that post.

Also please do both of the following commands exactly as shown:

echo "test message 1" | mail -s 'test mail 1' -r [email protected] [email protected]
echo "test message 2" | mail -s 'test mail 2' [email protected]
When you have done the above commands and answered the questions in the
post at
<https://mail.python.org/pipermail/mailman-users/2015-December/080249.html>,
I will respond further.
