Name
msys.cloudmark.score — Scan messages using Cloudmark
Synopsis
require('msys.cloudmark')
msys.cloudmark.score(msg, accept, vctx)
msg: userdata, ec_message type (optional) accept: userdata, accept_construct type (optional) vctx: userdata, validate_context type (optional)
Description
You must load and correctly configure the cloudmark module before using this function. Be sure to set the module option Enabled to false. This function can be invoked at the data, spool or each_rcpt phases. It will not work at the connect, ehlo, mailfrom or rcptto phases. msg is the email to be scored; accept is the accept_construct and vctx is the validation context. If any of these inputs are not provided, they will be inferred from the current context. Use this function to scan mail. A table is returned with the following key/value pairs:
-
score– The authority score for the message, a number between 0 and 100. The higher the number, the more certain the engine is that the mail is spam. -
is_spam– If the cloudmark module option MinimumScore is set, this item is set totrueindicating that the engine has determined the message is spam. No action is directly taken on the message; that is left to the user to do using a policy script. -
category– The category assigned to the message by the Cloudmark Authority. -
category-desc– The description of the category. -
sub-category– The sub-category assigned to the message by the Cloudmark Authority. -
sub-category-desc– The description of sub-category. -
rescan– If this flag is set to ‘yes’, the email would benefit from a rescan. -
analysis– The Cloudmark Authority analysis header.
The above name value pairs are also set within the validation context (VCTX_MESS).
Warning
Do not use pcall with this function.
