Hello team,
Good day!
I noticed that when I reply signed with public key included for a plain email for the first time, I get the following error message about checksum mismatch error.

This kindof confusing as the message says the message I just sent sounds like it has been altered in transit when in fact its not.
I think there would be check that missed and should not have assumption about checksum mismatch of my newly sent email?
