7 and later sendmail will
reject the file and log a possible attack:
SECURITY ALERT: bogus qf line bogus line here
Losing qffile: bogus queue line
This might represent a serious attack against your machine or site. If you get this
message, investigate at once.
11.5.6 Savemail Panic
In the rare event that sendmail cannot dispose of a bounced message, it will preserve
the qf file as a Qf file and log the message:
savemail: cannot save rejected email anywhere
Losing qffile: savemail panic
The sendmail program tries everything possible to avoid this state (including bouncing
the message, sending it to the postmaster, and saving it to a dead.letter file). Only
if all else fails will it preserve the qf file as a Qf file.
In general, this points to an alias problem with the user named postmaster or the
owner of a mailing list. Suchusers are special. They must be able to receive email
messages no matter what. They should be the names of real people, not the names of
further mailing lists.
