I want to be able to configure postfix to relay mail for a specific domain through a SMTP server. The history is that AOL is blocking one of my client's newsletters because not enough email gets sent from my server to have a good reputation. So they block it. BS if you ask me but that's not your problem :-)
Anyway, so my thought was to configure postfix to send just their mailing list domain's mail through a google apps account, their primary domain's email host. So I installed the mail relay plugin and tried to enable it for their mailing list domain. But of course you can't have the "relay mail for domain" enabled at the same time as "mail for domain enabled." But, mailman is dependent on the "mail for domain enabled" feature.
So my question is, could the "mailman mailing lists" feature have its dependencies changed to where either one of the two (relay or local mail) would satisfy requirements? Is there any reason why mailman would not work with postfix mail relays?
