NAME

postdrop - Postfix mail posting utility

SYNOPSIS


ppoossttddrroopp [--rrvv] [--cc _c_o_n_f_i_g___d_i_r]

DESCRIPTION

The ppoossttddrroopp(1) command creates a file in the mmaaiillddrroopp directory and copies its standard input to the file.

Options:

--cc _c_o_n_f_i_g___d_i_r The mmaaiinn..ccff configuration file is in the named directory
instead of the default configuration directory. See also the MAIL_CONFIG environment setting below.
--rr Use a Postfix-internal protocol for reading the message from
standard input, and for reporting status information on standard output. This is currently the only supported method.
--vv Enable verbose logging for debugging purposes. Multiple --vv
options make the software increasingly verbose. As of Postfix 2.3, this option is available for the super-user only.

SECURITY



The command is designed to run with set-group ID privileges, so
that it can write to the mmaaiillddrroopp queue directory and so that
it can connect to Postfix daemon processes.

DIAGNOSTICS

Fatal errors: malformed input, I/O error, out of memory. Problems are logged to ssyyssllooggdd(8) and to the standard error stream. When the input is incomplete, or when the process receives a HUP, INT, QUIT or TERM signal, the queue file is deleted.

ENVIRONMENT



MAIL_CONFIG Directory with the mmaaiinn..ccff file. In order to avoid exploitation
of set-group ID privileges, a non-standard directory is allowed only if:
· The name is listed in the standard mmaaiinn..ccff file with the
aalltteerrnnaattee__ccoonnffiigg__ddiirreeccttoorriieess configuration parameter.
· The command is invoked by the super-user.
