[Users] Click to see a reply that doesn't exist issue

[Ralf Mardorf]

Hi,

I noticed a Claws version 3.11.1-72-g9cbe67d annoyance.

When trying to replying to an email, but I get

"** error occurred on SMTP session
*** Error occurred while sending the message:
550 5.7.1 t2E9DUb3027409 This message does not comply with required
standards."

IOW no reply happened, the mail is marked as "Replied". If you
click to see the reply, Claws doesn't show any message, in any folder
anymore. It's needed to close Claws and then to open it again, to "get
back the mails".

Regards,
Ralf
