Dovecot v2.2. was extremely permissive regarding address syntax.
Dovecot v2.3+ tends to be more strict, but if there's really an
interoperability problem we can implement a workaround. First I'd
like to know what exactly is going on. For some reason, your
incoming mails have an envelope "from" address without a domain
part, which is normally not allowed and makes little sense for
messages exchanged on the internet. Any idea why that may be
happening?<br>
