42 The roundup mail gateway may be called in one of three ways:
43 . with an instance home as the only argument,
44 . with both an instance home and a mail spool file, or
45 . with both an instance home and a pop server account.
47 It also supports optional -C and -S arguments that allows you to set a
48 fields for a class created by the roundup-mailgw. The default class if
49 not specified is msg, but the other classes: issue, file, user can
50 also be used. The -S or --set options uses the same
51 property=value[;property=value] notation accepted by the command line
52 roundup command or the commands that can be given on the Subject line
53 of an email message.
55 It can let you set the type of the message on a per email address basis.
57 PIPE:
58 In the first case, the mail gateway reads a single message from the
59 standard input and submits the message to the roundup.mailgw module.
61 UNIX mailbox:
62 In the second case, the gateway reads all messages from the mail spool
63 file and submits each in turn to the roundup.mailgw module. The file is
64 emptied once all messages have been successfully handled. The file is
65 specified as:
66 mailbox /path/to/mailbox
68 POP:
69 In the third case, the gateway reads all messages from the POP server
70 specified and submits each in turn to the roundup.mailgw module. The
71 server is specified as:
72 pop username:password@server
73 The username and password may be omitted:
74 pop username@server
75 pop server
76 are both valid. The username and/or password will be prompted for if
77 not supplied on the command-line.

80 Same as POP, but using Authenticated POP:
