PMDF System Manager's Guide
PMDF-REF-6.0

/pmdf/bin/sendmail is designed for compatibility with mail user agent applications. However, it is not intended to be 100% compatible with sendmail when it comes to command line options for use by human users in submitting messages or management activities. PMDF's design has some fundamental differences from sendmail's design; PMDF as a whole provides a safer implementation of all sendmail's functionality, plus a great many additional capabilities. Not all sendmail command line options make sense for PMDF's sendmail replacement; the underlying functionality may be provided by PMDF in a way other than sendmail options.

Instead, for submitting messages from the command shell, see the pmdf send utility, described in the UNIX Edition of the PMDF User's Guide . For checking on the PMDF queues, see the pmdf qm utility. For listing currently executing PMDF processes, see the pmdf process utility. Or for other management activities such as testing address rewriting, see additional PMDF utilities described in Chapter 31 .

The command line options recognized by PMDF's sendmail replacement are shown in Table 17-1 .

-ruser	Synonym for -fuser
The following are always set when sending a message

In addition, any other options not specified here are not supported and are ignored with an error message.

When submitting to the local channel, i.e., invoking /pmdf/bin/sendmail, users may set the PMDF_FROM environment variable to specify their From: address. PMDF will insert a Sender: header line with the authenticated address if it is different than the From: address.
