I am using V6 beta 6, so yours may be different.
In TP offline - configure/email routing rules/mail rejection/
.. and POP3 rejects based on header (as long as the rejection rule can
get all the info from there).
For thought starters (for the current project) TP has following:
. was sent from user xxxxx
. has subject line containing xxxx
. is larger than nnnn bytes
. matches the custom rule, which can get quite sophisticated (using
perl-like regexps).
ie ^ is beginning
$ is end
\ escapes the next chr - ie converts it into a 'real' character.
. in regexp unescaped means 'any character'
QUOTE
Search patterns are expressed as regular expression. Study the following
examples, and pick out the one that most closely mirrors the type of
rule you want, then modify the rule to suit your purpose.
/^fred$/ All mail addressed to fred
/^fred@anycompany\.com$/a All mail from [EMAIL PROTECTED]
/@anycompany\.com$/a All mail from anybody at anycompany.com
/urgent/s All mail with "urgent" in the subject
/@anycompany\.com$/a & !/urgent/s All mail from anycompany.com
unless it has "urgent" in the subject
/^(tom|dick|harry)@/a All mail from Tom, Dick or Harry
!/^(tom|dick|harry)@/a All mail, except that from Tom, Dick or Harry.
/^X-Mailer:/h All mail with an X-Mailer header
