Email Forwarding

IMSS does not recommend forwarding email outside of Caltech.

To fight spam, many email service providers have tightened restrictions on sending and receiving mail. One result of these restrictions is that mail forwarded to these service providers (e.g. Gmail, Yahoo, Apple) may be spam filtered or outright rejected. Because we don't control the destination server for messages forwarded offsite, we cannot guarantee 100% email delivery, or determine what happened to an undelivered message after it exited Caltech's mail servers.

Your Caltech Office365 mailbox is protected by a variety of email security features and technologies. If you forward your email, you lose many of the benefits that our mailbox protection tools provide, since these tools won't be able to act on malicious messages that have been delivered to an offsite mailbox. IMSS also will not be able to proactively monitor access to your mailbox for anomalous activity, and in the event of a security incident involving your mail or access to your mailbox, we will have very limited ability to assist you in determining what happened.

If you would still like to get your email forwarded, please note:

• requests to forward email offsite are subject to supervisor approval for staff, including postdocs
• upon setup, direct forwarding is the default
• storing and forwarding email is available upon request

Instructions

1. If a forward is absolutely necessary, request a direct forward via Caltech Help (Request Type: IMSS > Email & Calendar > Forwarding Email (Add\Remove\Update) Request Form). NOTE: Requests by Caltech staff to forward mail offsite are subject to supervisor approval.
2. Encourage your correspondents to email your destination address directly.
