Hi everyone, We are about to switch the mail servers. This should be the final email sent from the old stack. We will send out another annoucement from the new server when it is switched (which should be in the next couple of hours). If you do not receive the next announcement, check your mail client config. For up to date instructions on how to configure Mutt to connect to the new mail servers, see here: https://wiki.redbrick.dcu.ie/index.php/Mutt#Connecting_to_the_mail_servers Regards, m1cr0man @ Redbrick Admins

Updating our mail system (Action required)

Hello brickies! I hope you liked our totally unformatted announcement a second ago - sorry about that! Ironically, it's part of the reason for this email. We have been working on a massive overhaul of our mailing infrastructure over the past few months. The time has finally come to announce that we will be switching our old mail stack over to the new stack, and what this means for you. # When is it changing? Monday, 27th April # What do I have to do? If you use Redbrick's Webmail, or your Redbrick email is forwarded to DCU, you don't need to do anything! Otherwise after Monday, if you want to connect to our mail servers to send or receive mail directly, these are the new credentials for your client: IMAP server: mail.redbrick.dcu.ie IMAP port: 993 IMAP security: SSL/TLS SMTP server: mail.redbrick.dcu.ie SMTP port: 587 SMTP security: STARTTLS SMTP login required: yes IMAP/SMTP username: YOURNAME(a)redbrick.dcu.ie IMAP/SMTP password: YOURPASSWORD # What is changing? If you receive your Redbrick mails to your DCU address, then nothing will really change. What you may notice is an increase in valid mails and a decrease in spam. However if you are accessing your mail directly from your Maildir, or over IMAP, things are changing quite significantly. Mail is no longer being stored in your ~/Maildir folder. Instead, it is now stored in a separate directory where we can make a whole lot of optimisations and improvements to how we deliver and store mail. Next up, we are dropping support for insecure IMAP and only supporting IMAPS. This is also the only protocol we now support for reading mails, meaning in order to read mail on the terminal you will need "mutt" or similar. We are also dropping support for sending emails unauthenticated. You must connect with your Redbrick username and password to send mails now. Lastly, with our now updated system we took the time to update Mailman and migrate ALL our lists to Mailman 3. This means you can now log in and view, manage and unsubscribe from all your lists. However, one other awesome thing you can do is browse our massive archive of lists from clubs + societies past. Ever wondered what the Redbrick announce said in 1999? # Why are you changing mail? Our current mail stack is too old to be maintained. It is suspect to numerous security issues, it is too easy to spoof mail through our current servers, and we also process a lot of spam. With this ground-up redeploy of mail we have fixed all our current security issues, as well as brought in a bunch of new features: - Harder accidental sending of announcements - Faster sending of mail (3 seconds from us to Google) - Faster reading and searching of mail - Encrypted transfer of mail where possible - Machine learning on our spam filtering based on how users treat mail - No more spoofed addresses - Better mailing list management for users and admins If you have any further questions on the matter, reach out to m1cr0man via email and he will respond as soon as possible. Regards, m1cr0man @ Redbrick Admins
