Generic Email Setup Information

Until 2025, when hosting your domain email at HIS we used to recommend using the hosting server name as hostname in email apps settings: zimbraxx.his.com or psaxx.his.com
In 2025, we are transitioning to using a more portable mail host name format:

If your domain is: domain.ext, the email hostname should be: domain-ext.his.com
This way you won't have to update your email settings if your hosting account is moved to another server.

The following are the settings for setting up and configuring your @his.com mailbox.

Mail server settings

• Incoming mail server (IMAP): domain-ext.his.com (or mail.his.com if you have an @his.com or @hers.com mailbox)
• Incoming Server Port Number: 993 Security: SSL/TLS
• IMAP Root Folder: INBOX
• Outgoing mail server (SMTP): mail.his.com or zimbrax.his.com or psaxx.his.com
• Outgoing Server Port Number: 465 Security: SSL/TLS
• Full Name.
• Username: use your full email address
• Email password (for example, password1)
