On systems that allow a user to belong to one group at a
time, failure stops here with the check for that one group. On systems that allow users to
belong to many groups at once, failure causes sendmail to check the other groups to which
the controlling user might belong. It finds the list of groups by calling getgrgid(3).
If your system lacks the getgrgid(3) call or doesn??™t need it, you should exclude this code by
defining NO_GROUP_SET in sendmail/conf.h. NO_GROUP_SET causes the code
containing the call to getgrgid(3) to be excluded from sendmail. Be aware that excluding
getgrgid(3) support on systems that need it can cause delivery to files to fail in mysterious
ways.
If you are running a precompiled version of sendmail, be aware that there is no debugging
switch that can tell you what the setting of NO_GROUP_SET was set to at compile time.
Note that NO_GROUP_SET affects only inclusion of the getgrgid(3) system call. See the
DontInitGroups option (?§24.9.41 on page 1023) for a means to exclude the getgrgid(3) and
initgroups(3) system calls by means of your configuration file.
New ports should be reported to sendmail@sendmail.org so that they can be folded into
future releases.
3.4.39 NOTUNIX
Exclude ???From ??? line support Tune with confENVDEF
Under Unix, a file of many mail messages normally has one message separated from
another by a blank line and then a line that begins with the five characters ???From ??? (four
letters and a space).
