MCN Webmail System:We have changed the page at to a new page which will allow you to go to both of our webmail systems. Both systems will continue to be active.

Moving Between the Two Systems--Folders and Messages: If you make a folder in the old webmail system, the new system will pick it up automatically. However, if you make a folder in the new system, you will need to go to the Folders area in the old system and subscribe to it. If you delete a message in either system it will be gone from both systems.


SSL and TLS Encrypted E-Mail Transmission
Now Available on MCN Mail Servers:

Overview: MCN has implemented secure TLS and SSL e-mail transmission for both our incoming and outgoing servers. These secure transmission protocols allow for encryption of your password and your e-mail messages to and from the MCN mail servers and are widely used in the ISP industry. These secure transmission protocols can be used from any Internet connection. These are good to use if you are away from home, using a wi-fi hotspot, or just want some additional security during transmission of your e-mail messages. We encourage .everyone to take advantage of this.

Using SSL/TLS Encryption: We have added instructions for turning on SSL e-mail for all of the major e-mail clients such as Outlook, Outlook Express, Windows Mail, Thunderbird, Entourage and OS X Mail to our Special E-mail Features Instructions

Spam Control, Powered by Magic Mail: MCN has partnered with Magic Mail to provide spam and virus control services for our customers. We have a Magic Mail info page with product information, and an FAQ (Frequently Asked Questions)

 MCN has now increased our standard mailbox size from 25 megabytes to 250 megabytes. Additional e-mail storage can be purchased for e-mail storage.

IMAP: MCN Does support IMAP. IMAP and webmail users should note that any files left in the trash folder more than two weeks will be deleted.

Autoresponders/Vacation Away Messages can be set up on your own, free of charge. Go to our Autoresponder Set-Up Instructions page to learn how to do this.

Sending E-mail When Outside of the United States: In order to cut down on spam attacks from overseas addresses, we're are now imposing a limit on the number of e-mail messages that can be sent from networks outside of the U.S.. If you are traveling outside the U.S., please limit your e-mail messages to a total of 100 recipients within a one hour period. This would be one message to 100 people or 10 messages to 10 people or 100 messages to 100 different addresses. If you exceed this limit, you will be "blacklisted" and unable to send mail or reach any MCN services until we clear your IP address. If you have questions or issues with the new policy, please call us or e-mail us. Again, this ONLY applies to MCN customers using the MCN outgoing mail servers to send e-mail on networks OUTSIDE of the United States.

MCN offers Private and Public Listservs. To find out more please click link:
