This afternoon, I received this email from GoDaddy.com, my web hosting service:
Important information about your hosting account
Due to spammers abusing MailMan - a cPanel feature that lets you send bulk emails - we're removing the feature on January 23, 2016
If you want to send bulk emails to your customers or clients we recommend checking out GoDaddy Email Marketing. Not only does this program let you email customers, it also includes more powerful features than MailMan, like opt-out management.
If you have questions or need assistance, contact our Support Team at (480) 505-8877.
Mailman is one of the services that I rely on for personal use, as well as for the web site and mailing list that I operate on behalf of MacinTech, a non-profit Macintosh User's Group here in the Denver area.
I've just spent a half-hour on the phone with goDaddy, and there is no exception to their decision to remove Mailman from the service that I've already paid for in advance. Their proposed solution is to pay them twice as much as I do now to add their email marketing program!
There are other hosting providers, like MacHighway, that offer hosting packages for LESS than GoDaddy, which include a mailing list manager, Dada Mail, which is similar to Mailman.
So, after many years at GoDaddy, I'll be canceling my service and domain registrations with them in January, and moving to MacHighway.
