- Running uk-sendmail 2.1 (under sunos 4.1.2) it seems that /usr/lib/sendmail
- core dumps if an incoming SMTP connection (eg from JIPS) specifies a null name
- in the sender in the envelope - ie if it opens up with :-
-
- MAIL FROM: <>
-
- Apparently this is just the thing to do when delivering error reports (rfc822?)
- and a local smail site has been filling our /usr/spool/mqueue with
- zero-length queue-files and an 8Mb corefile every 15 minutes. Good fun.
-
- SUN's sendmail.cf files all seem to have the smail-proofing rules :-
-
- | # handle "from:<>" special case
- | R$*<>$* $@@ turn into magic token
- | ...
- | R@ $@$n handle <> error addr
-
- but as far as I can see, standard uk-sendmail doesn't seem to buld this in.
-
- Has anyone fixed this already please?
