I’m talking about a nearly-automated @heick.email<\/em><\/p>\n For years, if you ever wanted to send me an email I would say:<\/p>\n “Just put your name at the front of @unliterate.net, and i’ll get it.”<\/p><\/blockquote>\n Ever since I setup my email @unliterate.net\u00a0wrong<\/em> as a catch-all SPAM domain, I’ve had to deal with the following rigmarole when getting new email setup:<\/p>\n Which things have been working for years, and it’s been a fairly straightforward approach.<\/p>\n Until I got married, and we decided to get the\u00a0heick.email<\/em> domain and have all our mail shared.<\/p>\n So, the @unliterate.net experiment utilized POP3 as the server for me to get all my catch-all. This was easy to configure, and was fairly straightforward.<\/p>\n We needed to be able to share email across computers and devices, though, and still have the flexibility to do the “folder structure”-thingy that I’ve grown comfortable with the @unliterate.net “mail filter” rules.<\/p>\n So, the only solution is to go from POP3 to IMAP.<\/p>\n IMAP gives us the flexibility of folders on the\u00a0server<\/em>, not on the client. It also stores all the mail there, and the protocol (after swallowing that it’s not like POP3) is actually quite orderly and simple.<\/p>\n So, i’ve employed dovecot as my IMAP server, which was also my POP3 server, and configured it simply to enable IMAP and know where I want my users mailboxes to be stored.<\/p>\n After setting up DNS for mail, i’ve got email coming into @heick.email, and I’m happy.<\/p>\n I just need to be able to\u00a0now<\/em> do the mail filtering…<\/p>\n This was a basic challenge, and I love challenges.<\/p>\n I had to use my programming language of choice (PHP) with the php-imap module loaded, and fancy up a script that runs on a *\/1 (1 minute) cron task.<\/p>\n The script is as follows:<\/p>\n To explain, basically this access my IMAP server, gets all the folders, then gets all the mail. It goes though the “to:” portions of the email addresses and sees if I have a folder that matches what’s in the\u00a0name<\/em> part of the email address in the “to:” portion. If it doesn’t exist, it makes the folder. Then, as a final result, it moves the mail to that folder and aborts.<\/p>\n So, this script now runs every minute, checking for new mail, creating the folders necessary and moving the messages.<\/p>\n vivre heick.email!<\/em><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" Yays!
