Clearly, the relevant specifications don't allow UTF-8 in the local part without email address internationalization (EAI), which Dovecot does not support nor announce yet (although that should be mended somewhat soon). My preferred fix for now would be to reject addresses like that, which would maybe still mean that this message is rejected entirely. Alternatively, that address at least needs to be skipped, ignored, or modified: all of which aren't very nice things to do. The alternative is forwarding this violation to other systems, which is seldom acceptable either.
Would accepting UTF8 local part in the From header have any negative consequences for Dovecot? If it does not I would accept it, based on the fact that it maintains greater interoperability with other systems. John
Depends on what causes the panic. I don't know that yet.
