Important information: POP, IMAP, SMTP, and Webmail Settings

It has been exciting and gratifying to see us move to the last stages of our infrastructure upgrade.  By and large, it has proceeded very smoothly considering the vast amount of work that has been undertaken.

I have been sending emails to the alert addresses entered by email administrators in the control panel, but a few customers have left that field empty or it has an old address, so that information hasn’t made it to everyone.

We are now migrating private label webmail sites over to the new system.  It is critical that all email client programs and customized DNS records have the correct information in order for your service to continue uninterrupted.

POP Setting:

IMAP Setting:

SMTP Setting:

Secure Settings: (for POP, IMAP, & SMTP)

Please note

The new system has the latest-and-greatest design and ability to load balance and hot-failover private label webmail sites.  However, the new system requires that the private label site *not* have the same hostname as your POP, IMAP, and SMTP settings (i.e. "" can no longer be the hostname for webmail + POP + SMTP).

Also, the hostname will continue to work for POP, IMAP, and SMTP so clients and CNAME records configured in this way are just fine.

And if you need a quick way to update your email configuration on a Windows PC, try the email auto-configuration tool mentioned in an earlier blog post:
