57 | ** ARPA MAILER -- Queue ARPANET mail for eventual delivery | |
58 | ** | |
59 | ** The standard input is stuck away in the outgoing arpanet | |
60 | ** mail queue for delivery by the true arpanet mailer. | |
61 | ** | |
62 | ** CUSTOMIZED FOR THE C/70 | |
63 | ** | |
64 | ** Usage: | |
65 | ** /usr/lib/mailers/arpa from host user | |
66 | ** | |
67 | ** Positional Parameters: | |
68 | ** from -- the person sending the mail. | |
69 | ** host -- the host to send the mail to. | |
70 | ** user -- the user to send the mail to. | |
71 | ** | |
72 | ** Flags: | |
73 | ** -T -- debug flag. | |
74 | ** | |
75 | ** Files: | |
76 | ** /usr/spool/netmail/* -- the queue file. | |
77 | ** | |
78 | ** Return Codes: | |
79 | ** 0 -- all messages successfully mailed. | |
80 | ** 2 -- user or host unknown. | |
81 | ** 3 -- service unavailable, probably temporary | |
82 | ** file system condition. | |
83 | ** 4 -- syntax error in address. | |
84 | ** | |
85 | ** Compilation Flags: | |
86 | ** SPOOLDIR -- the spool directory | |
87 | ** | |
88 | ** Compilation Instructions: | |
89 | ** cc -n -O -s arpa-mailer.c -o arpa-mailer -lX | |
90 | ** chmod 755 arpa-mailer | |
91 | ** mv arpa-mailer /usr/lib/mailers/arpa | |
