All mail services on EE have been migrated to Google as of 3/3/2010. The SMTP server will be shut down on 5/3. DO NOT continue using volt.ee.iitm.ac.in as your mail server any longer, as your mails may not be delivered as expected. All faculty, staff and students in the department should have already received a mail from migrate@ee.iitm.ac.in informing you of the procedure. If so, please do not continue using the Openwebmail service, as your mail will not be properly saved.
The old interface at old Openwebmail interface is only available for a short while, so you can continue to check / retrieve your old mail. This will be shut down by the end of March, 2010.
Please contact migrate@ee.iitm.ac.in if you have any queries in this regard.
