End of Support for SMTP Authentication Using CRAM-MD5
On June 26, 2013, we will be performing a maintenance on our Hosted Email and Microsoft Hosted Exchange environments which will remove the ability for mail clients to send mail using the legacy authentication protocol, CRAM-MD5. Once removed, a very small portion of our customers may lose the ability to send mail until their mail client's SMTP authentication method is changed.
Why are we making this change? We are continually striving to improve the quality, usability, and security of our mail offering. While CRAM-MD5 is a secure authentication protocol, the industry as a whole has been migrating away from using this mechanism. The recommended method for sending mail today is to use PLAIN/PASSWORD authentication over an SSL or TLS connection.
Will I be impacted? Our extensive testing in preparation for this maintenance has proven that the vast majority of mail clients do not use CRAM-MD5 by default. It is very difficult to pinpoint each and every mail client, version, device, etc that could be impacted, although we do know that if you are running one of the following configurations you could be impacted by this change:
- Apple Mail (Mac Mail)
- Apple devices still running legacy iOS versions (prior to IOS 6.x)
* NOTE: Customers using iPhones with Mobile Sync enabled will NOT be impacted.
I'm impacted / will be impacted... How do I fix this? If you feel you may be impacted, or after the maintenance is complete you are no longer able to send mail from your client, you can resolve this issue using one of the following means:
1) Re-configure your mail client so it does not use CRAM-MD5 authentication for SMTP (sending). We also suggest connecting to our system via SSL or TLS when sending mail.
2) Contact support and we can walk you through the process.
Is there a workaround while I'm trying to set this up properly? Absolutely! You can always login to webmail to access and send email like normal should you experience issues and need to send something quickly. The webmail login can be accessed here: http://webmail.emailsrvr.com.
Microsoft ActiveSync Issue
At this time, a small portion of our customers utilizing Microsoft Activesync to connect to our Exchange 2010 environment from mobile devices could be impacted by a software bug in the Activesync code which was recently discovered by our engineers. Symptoms include intermittent ability logging in as well as sending/receiving email from mobile devices using the Activesync protocol. We have taken measures internally which provide a temporary workaround to limit the extent of the impact, but affected users still may experience the symptoms described above. We are working closely with Microsoft while they develop the fix for this software bug, which we’re being told is in progress now. We apologize for the inconvenience this is causing you, and as a workaround you can still login to the webmail system from your mobile device to send and receive mail while we await the permanent solution from Microsoft.
Maintenance - Exchange 2007
As part of our efforts to continually improve our product offerings, we will be performing an emergency maintenance on our Hosted Exchange 2007 email platform. This maintenance window is scheduled to start May 15th, 2013 at 10:00pm CST and will run nightly until 4:00am CST.
During the maintenance, we will be performing mailbox moves for a small number of mailboxes. Users being moved will experience interruptions of connectivity to their Exchange 2007 mailboxes via POP/IMAP/SMTP/RPC over HTTPS and Outlook Web Access protocols.
