Good Day

I clicked on a web page link and claws-mail opened a compose window. I completed the message and sent it off on it's merry way.

The message was returned with,

"The following message to <Dr.???> was undeliverable.
The reason for the problem:
5.1.1 - Bad destination email address 'invalid domain "": no dot found'

The exact address (with substituted question marks) was,
" Dr. ???, DVM, MS, MPP <???@???.ca> "

I checked the accuracy of the address and resent it. The message bounced back to me again.

I edited the address to,

" Dr. ??? <???@???.ca>"

and it went through.

Something in the address is confusing the address formatter.

Hope this helps.

The string:

 Dr. ???, DVM, MS, MPP <???@???.ca>

is not valid as a single address because ',' is a character that must be quoted to be part of the address¹. The single address in the mailto link it should have been written as:

 "Dr. ???, DVM, MS, MPP" <???@???.ca>

Otherwise it's just a list of four addresses:

 Dr. ???
 DVM
 MS
 MPP <???@???.ca>

Which Claws Mail must handle as given because they are valid addresses, although some doesn't exist, hence the error you saw.
