The servers that facilitate email access have recently been upgraded. Not only are the new machines faster, but they are now using the same high-performance mail access server as our Webmail servers. We completed this upgrade primarily to provide faster access to mail, but there are also a few noteworthy positive side effects of the upgrade:

  • Log in when over quota - Users can now log in to both Webmail and these new servers if they are over quota. This will allow users to delete messages in order to get back under quota without needing CIT to temporarily increase their quota. When deleting messages while over quota, it's important to make sure that the deleted messages aren't being moved to a trash folder and are instead being instantly deleted.
  • Quota support for IMAP users - Most modern mail clients (Mozilla Thunderbird and Apple's Mail.app) support a feature of IMAP called IMAP Quota, which is now supported on our new mail access servers. Clients that support this feature will now prevent users from taking actions that would result in them going over quota. Instead of silently failing when such an action is initiated, the server will now respond with the error message "Quota exceeded (mailbox for user is full)".
    • Some mail clients that support IMAP Quota can display your quota usage so you know how much space you are using without calculating the sizes of all your folders. Currently, Thunderbird is the only modern mail client that shows your quota from the main interface:

Email access may seem slow the first time you login after this upgrade as the servers rebuild cache data. This sluggishness is only temporary, and should stop once the cache rebuild is complete. Please contact the CIT HelpDesk at 585-245-5588 if you have any questions.
