dovecot accept non ascii chars in the local part as it did until 2.2 (see attached patch) or 2) instead of the i_assert() call, log an error and reject the email. But this second approach looks more complicated. The patch just removes the i_assert() call. I tried that patch and it seems ok. Before applying it, it is worthwhile if anyone can remember what was the logic behind this i_assert() call in the first place (which I fail to see), in case there is something that I am overlooking.
