BSD w/ sendmail

BSD UNIX® can include the sendmail Mail Transfer Agent which supports 'miltering' (mail filtering) as an operational mode.

In this mode, portions of an arriving e-mail are passed to the miltering process for evaluation and classification as completed fields are assembled and become available.

EPA applies the mailbox Preference Set criteria to the field content presented to determine onward processing action.

The advantage to this field-by-field process is that rejection of an e-mail occurs at the earliest possible time.  The disadvantage is that EPA's post-classification processing options are limited by sendmail.

EPA uses the UNIX 'crontab' utility as the EPA Archiving Task scheduler.

EPA shell jobs use the Korn shell.

EPA can be shut down and restarted without rebooting the BSD Unix system.

Prior to installation, the hosting mail server operating system needs to be modified to:

1.  Create a directory for EPA use on the mail server at the domain root

2.  Create the account "epa_mailroom" with:

           o  Host directory as chosen.

       o  Password "EPA@<domain_name>" (without the extension ".xxx")

       o  "epa_mailroom" entered in 'ftpchroot' to permit FTP access only within the host directory.
