[listsb-amavis at bitrate.net]

hi-

i’ve set log_level = 5; while installing/configuring, and see the following logged during start:

Jun 10 20:06:13 server amavis[4190]: INFO: SA version: 3.4.0, 3.004000, no optional modules: auto::NetAddr::IP::full6 auto::NetAddr::IP::Util::inet_n2dx auto::NetAddr::IP::Util::inet_n2ad auto::NetAddr::IP::Util::inet_any2n auto::NetAddr::IP::Util::ipv6_aton

i believe i have these modules installed:

>dpkg -l libnetaddr-ip-perl

i’m just curious why amavis seems to indicate it doesn’t see them, and if that perhaps means i might be doing something wrong.  nothing in particular appears broken, strictly an inquiring mind.

i’m using 2.7.1 [and spamassassin 3.4.0] courtesy of ubuntu 13.10.

thanks
