premejslim o necem podobnym
postu mam jak ty (postfix, virtualni uzivatele a spamassassin), ale me
by stacilo ty spamy presmerovat na uzivatele "spam". Moje idea byla
zatim takova, ze pomoci header_checks mapy bych nedefinoval
/^Subject: .*SPAM* /
REDIRECT s...@moje.domena
zatim jsem to teda nezkousel, je to jen takova idea jeste nedotazena
do konce. Nejsem si ani jistej, jestli ten header_checks je aplikovan
jen na prvne prichozi maily, nebo i na maily vracene spamassassinem
s tim by mi moh nekdo poradit
No jestli muzu... nerikas jak dostanes zpravu do spamassassina.
Je vice cest.
Vsechny zpravy prochazi "cleanup"-em, ktery je soucasti postfixu a zde
se provadi"header-checks"
Problem je v tom, ze napriklad pokud spamassassin nakonfigurujes jako
"milter" (smtpd_milter = local:/var/run/spamass-milter.sock), tak zprava
nejdrive projde pres cleanup a potom teprve jde do spamassassina a tudis
radek hlavicky "X-Spam-Status: ..." je pridan az po "cisteni" zpravy a
tudis neprojde zminovanym header_checks.
Dalsi moznost je poslat zpravu do spamassassina pomoci smtp a
spamassassin ti to vrati na jiny port, kde samozrejme header_checks
zpravy presmeruje jak pozadujes.
Treti moznost je pouzit amavis nebo nejaky LDA, ktery ti dovoli
definovat pravidla.
Co se me tyce, tak mam variantu 1 (milter) a cekam az vyjde Postfix 2.7,
kde Wietse doprogramoval direktivu "milter_header_checks", ktera jiz
prochazi zpravy az po vsech definovanych milterech. Prikladam uryvek
emailu od Wietse a timto mu velmi dekuji:
-
I have added header checks for Milter-generated mail headers.
The feature is called "milter_header_checks".
It is available from Postfix mirrors as postfix-2.7-20090607, and
also available as an optional patch for Postfix 2.6.
Wietse
milter_header_checks (default: empty)
Optional lookup tables for content inspection of message headers that
are produced by Milter applications. See the header_checks(5) manual
page available actions. Currently, PREPEND is not implemented.
The following example sends all mail that is marked as SPAM to a spam
handling machine. Note that matches are case-insensitive by default.
/etc/postfix/main.cf:
milter_header_checks = pcre:/etc/postfix/milter_header_checks
/etc/postfix/milter_header_checks:
/^X-SPAM-FLAG:\s+YES/ FILTER mysmtp:sanitizer.example.com:25
The milter_header_checks mechanism could also be used for whitelisting.
For example it could be used to skip heavy content scans for DKIM-
signed mail from known friendly domains.
This feature is available in Postfix 2.7, and as an optional patch for
Postfix 2.6.
