Здравствуйте.
Система FreeBSD 5.4
Postfix 2.2.5
ClamAV 0.87
clamsmtp 1.5
SpamAssassin 3.1
Хочу что бы письма которые приходят с локального адреса(от Exchange) не проверялись SpamAssassin, но проверялись антивирусом ClamAV.
Только с помощью clamsmtp неполучалось, поставил еще proxsmtp-1.2.1
в proxsmtpd.conf указал
OutAddress: 10056
FilterCommand: no filtering
# The type of filter ('pipe' to pipe data through filter,
# or 'file' to pass a file to the filter)
FilterType: pipe
Header: X-Filtered: By ProxSMTP
KeepAlives: 0
XClient: off
Listen: 127.0.0.1:10055
TempDirectory: /tmp
TransparentProxy: off
User: clamav

Но на внутреннем интерфейсе почта не ходит, в логах следующее
Nov 23 05:07:40 free1 postfix/smtp[997]: 6FE8A170B5: to=<xxx@xxx.ru>, relay=none, delay=0, status=bounced (mail for mail.domain.ru loops back to self)

Если написать так
192.168.0.25:smtp inet n - n - 10 smtpd
     -o content_filter=filter:dummy
то в логах следующее:
Nov 23 05:26:33 free1 postfix/smtp[1217]: 236E5170AD: to=<xxx@xxx.ru>, relay=none, delay=0, status=bounced (Host or domain name not found. Name service error for name=dummy type=A: Host not found)
