Our mail service uses industry standard protocols (IMAP, SMTP) and will work seamlessly with any mail program you choose to use. We recommend Thunderbird for most people.  For iOS, Airmail and Spark are good options, but the default mail and calendaring apps work as well. For Android, Edison, Bluemail, and K9 are all good options, with K9 being the best for end to end encryption. The default mail apps on Android should work fine as well.

Most mail app should autodiscover the mail settings needed for your paxmail.cc address, but if they do not and you need to enter the details manually, they are:

Your username will be your whole email address.

If you have your own domain, you will need to set your DNS records to point to PaxMail for sending. When you log in to the administrative portal, you will see a section named "Domain Records" which will list all of the records you need to set up.
