The mailing list for listmasters using Sympa

["Lese Ratte" <address@concealed>]

Hi @all,

(I'm sorry, my english is bad.)

AOL does not like the way Sympa is installed on my server sending emails. What
can I do?
An Email send by Sympa looks like this, if someone with an aol-email-address
(person1) sends an email to a mailinglist:

From: person1 <email@aol>
To: mailinglist@my-server

AOL complains: "my-server is not allowed to send email in name of aol"
Silimar error messages comes from gmail, so someone with gmail can not read
the email from person1 send by mailinglist.

Well. Yes, technical the server with sympa is sending email "in name of aol".
Everyone with domain "my-server" can read and send emails without error.

How can I configure sympa to change it to this:

From: person1 <mailinglist@my-server>
To: mailinglist@my-server

I found in the web config too many options, I'm lost. What can/should I do?
I tried "reply_to_header", "apply" (to "forced") but that changed nothing.

Or is there a better way?

Greetings
