[Mailman-Users] Using Mailman in a corporate environment with Exchange 5.5...

[Bill Hilburn]

Create a custom recipient named "list" (your list name) and forward it to 
list at listbox.corporate.net (again <your list name>@listbox.corporate.net).

Example:

I want a list called "NOC at mycompany.com".

Create a custom recipient on the exchange box named "NOC" and forward the mail 
to NOC at listbox.mycompany.com

> Every time I send an email to a test list (for example,

> Exchange Server 5.5 strips the "hostname' from the email address:

> 
> The Listbox is running RedHat 8.0, Sendmail, and MailMan 2.0.13
