At IU, why am I not receiving all of my email?
If you are not receiving all of the email sent to your Indiana University email address:
- The messages may have been misdirected. This can happen if:
- The messages may have been blocked. This can
- A sender outside IU sends mail to your fully specified Exchange address.
- Your email account exceeds its size limit.
- A message contains an attachment that is blocked by your mail filter.
- The source email system has exceeded the UITS bandwidth limit.
Exchange account mail forwarding issues
You can configure mail forwarding so that
messages sent to your IU email address (e.g.,
firstname.lastname@example.org) are forwarded automatically
to your account on another email service (e.g.,
email@example.com). However, if
your IU email account is on IU's Exchange service, email sent to your
IU email address from other IU Exchange accounts will bypass the
forwarding you set and land in your Exchange mailbox.
If you want to use another email service to read mail sent to your IU email address, including email that's sent from other IU Exchange accounts, you must create a forwarding rule on the IU Exchange server in addition to setting up forwarding; see In Microsoft Outlook for Windows, or in Outlook Web App (OWA), how do I automatically forward all of my IU email to another address?
Mail forwarding loops
If people emailing you receive bounce-back messages that mention "excessive recursion", the problem is most likely due to a mail forwarding loop. You can inadvertently cause a mail forwarding loop by configuring mail forwarding in such a way that email sent to you has no final destination.
To fix this problem, make sure your primary email address and mail forwarding settings are properly configured; see:
- At IU, how do I choose or change my primary email address and preferred email service?
- At IU, how do I forward my email?
A problem can occur in the IU email address database if you encountered an error while creating your accounts, or if you left the university temporarily and needed to have your accounts re-enabled. The relevant database updates overnight, so changes you make may not take effect until the next day. If your problem persists, contact your campus Support Center for help.
Mail sent to fully specified Exchange addresses
Any message sent to your fully specified Exchange account address
firstname.lastname@example.org) from an
email system outside IU will be rejected and generate a bounce message
to the sender. Make sure your contacts outside IU know to use your
primary IU email address (e.g.,
Mail exceeding your storage allotment
Mail with blocked attachments
UITS maintains mail filters that block attachments that commonly contain viruses, or that are protected or contain protected content. This blocking behavior varies, depending on an attachment's origin, so it is sometimes possible to receive messages with these types of attachments; see At IU, what types of attachments are blocked from my email account?
Mail exceeding bandwidth limits
One of the ways IU protects its email system from huge volumes of spam is by limiting each host to sending only several hundred messages per minute. If someone is sending email from a non-IU host that has exceeded its bandwidth limit, that email may not get through to you; see What does IU do to protect users from spam and virus-infected email?
The architecture of IU email systems separates internal university mail flow from the rest of the Internet, providing a layer of protection that allows IU email to flow reliably between its students, faculty, and staff members. For this reason, it is expected that all official university email is sent via the IU system, and not through external, non-IU hosts; see At IU, what is the policy about official communications from the university to students?
