Hello/Hi/Greetings,

I'm having trouble emailing notifications since upgrading my machine to Ubuntu 20.04 LTS - when I send the notification, one email goes out (to whoever's now at the top of the list) and then it seemingly times out saying "The maximum time for sending email has been exceeded. Remaining emails have been skipped".

I can email notifications this way one-by-one but does anyone have any suggestions on what's causing this timeout so I can do them in batch again?
