From reading the ticket, I suspect the problem is in msmtp, an SMTP
client, a replacement for one function of sendmail. Sounds like msmtp
doesn't convert local to network in outgoing mail.
So the problem would seem to be in msmtp. Thank you Kurt!
Well, the problem might originate in msmtp, but I think opensmtpd also
has an issue here in that it breaks / locks up / hangs when presented
with this unexpected input, with possible security implications. If
not already done so, the original reporter might want to open a report
for this with the opensmtpd team.
