dovecot - Jul 2019 - lmtp with non ASCII Parameters changed in dovecot 2.3

Hi,

I updated from 2.2 to 2.3 and noticed lmtp rejects parameters
containing non ASCII now. this worked with dovecot-2.2 lmtp.

the string is already denied after reading in
"smtp_command_parse_parameters()"

mail from:<blu?>
500 5.5.2 Invalid command syntax

is there a plan to change this behaviour, or to implement the SMTPUTF8
extension in lib-smtp?




I guess thie would fix Michals "Dovecot LMTP rejecting mail from address
with apostrophe" Problem too.

this was a bad example. the problem is more common on rcpt to: if you
deliver to usernames or special folders

rcpt to:<?ser>
or
rcpt to:<user+sp?m at domain.org>
