    I do have to say for the purpose of tinkering I love these bigger projects because you learn so much on the way. Now having read your answer I am even more exited to try it out :D

    That’s awesome to hear! Welcome, and have fun! :)

    I haven’t heard of most of your abbreviations/term till now

    Oh, my apologies. Here is a definition list :

    • SMTP : Simple Mail Transfer Protocol : the base of any mail system, it’s the server you contact to send emails, which relay your mail to an other SMTP server, which store the mail for user to retrieve
    • IMAP : Internet Message Access Protocol : one of the protocols that can be used to retrieve emails from your mailserver (the other one being POP3)
    • SPF : Sender Policy Framework, a configuration on your domain name specifying which machines are allowed to send mails in its name
    • DKIM : DomainKeys Identified Mail : a signing process (signing each mail) to validate the “From” email address is indeed coming from the domain it pretends to
    • DMARC : a warning system to let you know when someone pretended to be you
