Questions related to Gryph Mail

Answers

What file types are blocked and cannot be uploaded or sent as attachments?

September 14, 2017

Beginning in August 2017, the Information Security team will be updating our mail filters to block additional potentially dangerous executable file types from reaching University mailboxes. We recognize that this may cause some disruption for email users, however we feel that the risk outweighs the end-user impact. 

Please note that if a file is blocked, the email will still be delivered and that attachment replaced with a text file with the following message "Dangerous file types are blocked for your protection. For any additional questions, please contact the administrator." If the file is required, please contact the CCS Help Centre for assistance (519) 824-4120 x58888 or 58888help@uoguelph.ca.
