In an effort to combat virus infiltration OTS implemented a policy regarding the exchange of .zip files. Zip files may be shared internally within the local UB Exchange email system without extra steps.
E-mails with a .zip file attached sent to an external (non-UB) address and those sent from an external address to a UB one will be blocked. When a .zip file is sent to an external email address, an undeliverable message will be returned to the UB sender with a brief explanation of our policy. Also, if a non-UB account sends an email to a UB address with a .zip file attached, the message will come through but with the zip file removed and an explanation inserted explaining our policy.
Only UB senders and recipients are informed of this zip filtering policy. Non-UB senders and recipients will not receive any bounce back or informational email explaining that the zip file did not go through.
If you need to email a .zip file to someone outside the UB community, or vice versa, you will need to change the extension of the .zip file. Please see the instructions below:
The same steps must be followed when an external user needs to send a UB user an email with a file attached.
