22 /* Important notice: defining MAIL_USE_FLOCK or MAIL_USE_LOCKF *will
|
|
|
23 cause loss of mail* if you do it on a system that does not normally
|
|
|
24 use flock as its way of interlocking access to inbox files. The
|
|
|
25 setting of MAIL_USE_FLOCK and MAIL_USE_LOCKF *must agree* with the
|
|
|
26 system's own conventions. It is not a choice that is up to you.
|
|
|
27
|
|
|
28 So, if your system uses lock files rather than flock, then the only way
|
|
|
29 you can get proper operation is to enable movemail to write lockfiles there.
|
|
|
30 This means you must either give that directory access modes
|
|
|
31 that permit everyone to write lockfiles in it, or you must make movemail
|
|
|
32 a setuid or setgid program. */

35 * Modified January, 1986 by Michael R. Gretzinger (Project Athena)
|
|
|
36 *
|
|
118
|
37 * Added POP (Post Office Protocol) service. When compiled -DMAIL_USE_POP
|
|
0
|
38 * movemail will accept input filename arguments of the form
|
|
|
39 * "po:username". This will cause movemail to open a connection to
|
|
|
40 * a pop server running on $MAILHOST (environment variable). Movemail
|
|
|
41 * must be setuid to root in order to work with POP.
|
|
|
42 *
|
|
|
43 * New module: popmail.c
|
|
|
44 * Modified routines:
|
|
|
45 * main - added code within #ifdef MAIL_USE_POP; added setuid (getuid ())
|
|
|
46 * after POP code.
|
|
|
47 * New routines in movemail.c:
|
|
|
48 * get_errmsg - return pointer to system error message
|
|
|
49 *
|
|
118
|
50 * Modified August, 1993 by Jonathan Kamens (OpenVision Technologies)
|
|
|
51 *
|
|
|
52 * Move all of the POP code into a separate file, "pop.c".
|
|
|
53 * Use strerror instead of get_errmsg.

|
|
|
239
|
|
|
240 If your system uses the `flock' system call for mail locking,
|
|
|
241 define MAIL_USE_SYSTEM_LOCK in config.h or the s-*.h file
|
|
|
242 and recompile movemail. If the s- file for your system
|
|

243 should define MAIL_USE_SYSTEM_LOCK but does not, send a bug report
