I think you need to determine where the problems occur.
qmail will say "host not found" if there is no information on that host
in DNS. If your DNS is set up wrong, this may happen because your
server lies to qmail. Another reason is that ISPs disable MX lookups. A
third (most common and a temporary error) is that there is no
authoritative name server for the address. This is common if none of
them can be reached (they are all on a bad net or you are) or (less
common) misconfigured. I would not be surprised if OE and MS-E would
happily send messages based on non-authoritative info, though.
OE (at least normal use) contacts qmail as an SMTP client. It does all
the header writing. Qmail doesn't. Qmail may change the envelope
address by canonicalizing the address, but it does this correctly. If
nyaf.se is a CNAME for nyaf.seyes (broken DNS) this might happen.
However, I'd bet on OE being the culprit.
