As the titel say I am lokking for a decent self hosted autoresponder solution, not interested in Aweber and others similar I want it all on my own server

Also if it behaved similar to Aweber ie allowing others to sign up for a monthly fee that would be great.

Anyone got any ideas? Sick of googling same old junk coming up such as Interspire and Alstrasoft must be something a bit more professional out there with better support not interested in the price tag its just got to do what I want it to.

Any suggestion and indeed links appreciated

Thanks

Chris
