Email delivery delays - June 28

Thursday, June 28, 2018

What is happening? Users have been experiencing delays in email delivery from University of Waterloo email accounts due, in part, to the disabling of TLS 1.0. IST has implemented a workaround and the backlog of queued emails are now being delivered.

Important note: As well as this current issue, we are still seeing email delays due to the blacklisting problem from the previous week. For more details see: https://uwaterloo.ca/information-systems-technology/news/email-uwaterlooca-blacklisted

When is this happening? Delays began following the disabling of TLS 1.0 on Tuesday, June 26 (The blacklisting issues began around Wednesday, June 13).

Questions or concerns? Please contact the IST Service Desk, helpdesk@uwaterloo.ca or ext. 44357.
