Help -- Sent email not received

[cmyoung]

On my Apple MacBook, since I did a restart on April 26 none of my Sent emails have been received by any recipients, even though they are in the Sent  folder of both the Apple email AND the Telus webmail site!!  (and I can send successfully from the Telus site).

Any ideas?

In addition, messages were received just fine by Gmail.com and Outlook.com recipients, just not Shaw.ca or Telus.net!!  An Apple support guy guided me through deleting and re-instating my Apple email account, and (after waiting for 12,000 messages to be re-downloaded) there was no change, so Telus it's in your court!
