Package: postfix Version: 2.11.1-1 Severity: wishlist I am updating some postfix settings while moving to a newer version and I currently have
milter_protocol = 2 in main.cf. I wondered if maybe that was old and it should be updated, so I started researching. I found http://www.postfix.org/MILTER_README.html which states The default version is 6 (before Postfix 2.6 the default version is 2). and http://www.postfix.org/postconf.5.html#milter_protocol which states that Sendmail 8 mail filter protocol version 6 (default with Sendmail version 8.14 and Postfix version 2.6). So milters that use libmilter1.0.1 version 8.14 or newer should be OK with upping the protocol to version 6. Even squeeze had '8.14.3-9.4'. apt-cache rdepends libmilter1.0.1: amavisd-milter clamav-milter libbobcat3 libmilter1.0.1-dbg libmilter1.0.1:i386 libmilter-dev libsendmail-milter-perl milter-greylist mimedefang opendkim opendmarc python-milter sm-archive spamass-milter There is only one package with milter in the description not listed (or depends of/on) above: libsendmail-pmilter-perl Which is a pure perl implementation of the Sendmail Milter protocol and was last released upstream on Apr 16, 2011. The debian/changelog mentions a test for milter versions up to 6, but I didn't determine versions supported. So, all milter packages in Debian should be pretty safe with using 'milter_protocol = 6' I think. So here is my wishlist bug, please consider adding something to the Debian documention like: milter_protocol: Nearly all milter packages in the Debian archive use the libmilter1.0.1 library which as of version 8.14 supports sendmail milter protocol version 6. The postfix default, starting in version 2.6, is 'milter_protocol = 6'. If you are migrating a older postfix configuration that specifies a lower version, it should be safe to remove and depend on the default. If you are using milters not provided by Debian, you may need to ensure compatibility. For more information please see http://www.postfix.org/MILTER_README.html Sound OK?
