Here's what should be some useful ACLs to break down elements of the
From header into the name part, email part, and domain part.
I'm planning to post these on the Wiki as examples. Perhaps someone
would check and optimize the regex befor I post it. I'm not the best at
regex.
# Extract the name part of the from address ("Name Part"
<[EMAIL PROTECTED]>)
# into $acl_c_from_name_part returning [Name Part]
warn set acl_c_from_name_part =
${sg{$h_From:}{\N^["]?(.*?)\s?["]?\s?<.*$\N}{\$1}}
# Extract the email part of the from address ("Name Part"
<[EMAIL PROTECTED]>)
# into $acl_c_from_email_part returning [EMAIL PROTECTED]
warn set acl_c_from_email_part =
${lc:${sg{$h_From:}{\N^.*<(.*)>$\N}{\$1}}}
# Extract the email domain part of the from address ("Name Part"
<[EMAIL PROTECTED]>)
# into $acl_c_from_domain_part returning [address.com]
warn set acl_c_from_domain_part =
${sg{$acl_c_from_email_part}{\N^.*@(.*)$\N}{\$1}}
