4: Usage:
5: sendberkmail [-m mach ] [-f addrfrom] [-h hopcnt] -t addrto
6:
7: Archaic Usage:
8: sendberkmail mach:user
9:
10: Send remote mail to user on mach.
11: Only one addrto allowed.
12:
13: Sendberkmail uses the network to send an mmail command
14: to the remote machine. It specifies the source, destination,
15: and a hop count only.
16:
17: Sendberkmail uses the -q option of net, so only error msgs
18: and non-zero return codes will be sent back.
19:
20: It is best to think of sendberkmail as a transport mechanism:
21: It takes mail from one machine to another machine (specified
22: using the -m option) and executes the local mail program
23: there with a to-address of "addrto", and a from-address
24: of "addrfrom". If the -m option is not given, it parses the
25: "addrto" field to get a berkeley network address.
26: This extreme generality is necessary when destinations are on
27: different networks, consider a command from the Ing70:
28:
29: sendberkmail -m csvax -f schmidt@parc -t research!chuck
30:
31: This is clearly a forwarding function- send mail from the Arpanet
32: to the Bell Net, which calls our CSVAX.
33: Alternatively, executed on the CSVAX,
34: sendberkmail -m ing70 -f research!chuck -t schmidt@parc
35: sends mail the other way.
36:
37: There is duplication in the arguments because of
38: a need to convert to labelled parameters.
39: See the note in mmail.c to that effect.
40:
41:
42: Options:
43: -t addrto mail command on remote machine will be
44: fed "addrto" as address
45: -f addrfrom mail will be "From" addrfrom
46: -m mach send this mail to the "mach" machine
47: -h hopcnt if this hopcnt hits a threshold, there
48: is presumed to be an infinite loop.
