I've been asked by my company to look for a program that will send a (subscribed) bulk email.
It must be able to send html formatted emails and provide auto unsubbing.
I've so far installed postfix and thunderbird mail client to my server and have succesfully sent a test email both to external addresses.
I'm looking at mailman to manage the list but am unsure if this is the correct program to use.
Has anyone got any suggestions?
