Description:
- If the if pmx-relay test is "false", and the else control is executed:
- Mail is assumed to be from an external host.
- The pmx_add_header command adds a header to the message. The header
includes the string "
X-PMX-Version
" and the PureMessage version (which is added
using the %%PMX_VERSION%% template variable.)
- The size of the message is then written to the message log. The
%%MESSAGE_SIZE%% template variable is substituted for the actual size of the
message, in bytes.
- The pmx_virus command tests the message for virus threats. If the test is
"true", and the message contains a virus:
- pmx_file copies the message to the quarantine with the reason
"Virus". This action does not affect the delivery of the message.
- The pmx_virus_clean action attempts to clean the virus from the message.
If cleaning fails, the message is quarantined, and a message is sent to the recipient based
on the specified failure template file, cantclean.tmpl.
- The pmx_replace_header command prefixes the "Subject" header with "
[PMX:VIRUS]
". The original "Subject" is added to the end of the header with the
%%SUBJECT%% template variable.
- The pmx_replace_header command then adds, or alters, a
"X-PerlMx-Virus-Detected" header. The %%VIRUS_IDS%% template variable
adds the found virus IDs to the message header.
