This is actually what happens in MailMate. The message is reopened in 
the composer and a sheet shows the SMTP error reported (verbatim). (It 
doesn't even block MailMate as many of the IMAP errors unfortunately 
still do.)

(But I know there are many other cases MailMate does not handle 
gracefully.)

You wouldn't happen to know why Yahoo rejects a message with a single 
URL? Is this some kind of spam-detection and if it is, why do they 
suggest adding text to the message (hmm, maybe this is a message 
intended for their web interface)?
