Hmm ... I don't add users, no, it's just me, and I have no idea if I can add users. What I do though is use different prefixes for emails with companies -- if I sign up with TMobile, for example, I'll register my email with them as 'tmobile@<mydomainname>.com' and can track them that way. I can implement custom sieve rules on FM, and have, but I want to write a script to generate my sieve rules and then upload them automatically, rather than cutting and pasting. I'd also like the ability to autoreply to senders not on my whitelist or otherwise managed in sieve, asking them to reply with a specific text in the Subject line so it gets to me. Most emails I don't ever want, and solicitation or marketing cold emails I don't want, and this might enable me to not have to even see them unless someone really wants to get my attention.
