Opensource vs solutions
Milter products listed in this document are classified as commercial or open-source solutions.
For each solution the URL and the following information is specified :
- category : SPAM, ATTACHMENT (attachment-blocking), VIRUS, SCRIPTABLE, DISCLAIMER, ARCHIVING
- status : maintained if software still being developed (latest version)
- mailing list URL
Few Milter solutions are multi-purpose ones : most of them try to address
one given need (virus-scanning, antispam, ...). Remember you can use
several Milters (several INPUT_MAIL_FILTER definitions in the .mc file)
if a single one does not offer all the features you need
Most commercial Milter solutions are antivirus filters : virus vendors
have adopted Milter quickly.
Which solution is to be used ? It all depends on your needs, knowledge,
time and money. Contact the author/company or use the proper mailing-list/newsgroup to check that the Milter solution you noticed will be appropriate.
