i-SENSYS MF657Cdw #806 error when sending scan to one particular e-mail (other works)

[Marooned]

Hi

I've recently bought i-SENSYS MF657Cdw printer and set it up but found out quite strange behavior. Scan to e-mail works fine to a few tested e-mail addresses except for just one which result in error #806. All mails (receivers and also the main from which the printer is sending those scans) are in gmail.com domain. I've logged into that main mail and there is no issue with sending manual mail from that one particular recipient. I've tried to look for that 806 error but all I could find was people had issues sending anything. I don't. Only that one recipient (and quite important one so I would like to solve that out).

Thanks for any hints.

Thanks for the reply. While it didn't help me 😉 I would like to close this as I found the reason and it was soooo lame.. There was a space at the end of the e-mail address and looks like Canon software forgot to just run trim() function on user input. Would be good to add it as it's quite common procedure. Anyway, problem solved by removing the space.
