Hello,
I start testing Evolution with Spamassassin, as I usually use
Thunderbird, but would be interested to compare the advantages
of having integrate calender, schduler, and so on.
When I lounched the download, I got a few more packages that are
suggested, and watching with apt-cache show (or aptitude show, I tried
both) I can't get an idea of what could be useful or not.
I use an only muchine.
Those packages are as follow:
Suggested:
> libnet-smtp-perl libmail-spf-query-perl razor libnet-ident-perl libdbi-perl
> dcc-client pyzor
The infos I get are following:
>0) $ aptitude show libnet-smtp-perl
> Package: libnet-smtp-perl
> State: not a real package

?
>1) $ apt-cache show libmail-spf-query-perl
> ...

> The Sender Permitted From (SPF) protocol relies on sender domains to

Seems interesting Is this one difficult to handle for newbees such as I
one year old newbie ? (don't rewrite easily in configuration files yet,
I must ask for advice about what to change each time I need to, except
the source.list of course)

Looks nice, but the last one in the list, Pyzor would be the very free
equivalent....
>3) $ apt-cache show libnet-ident-perl

I don't use database yet, so it's of no need for me...
>5) $ apt-cache show dcc-client

Ok, for big enterprises...

So, my question is: for the n°0, 1, 3, 6, and maybe 2 for razor, do
people here dowloaded them and is able to say what are the most useful
and the most efficient ? (razor/pyzor, the very use of
n°3:libnet-ident-perl and any interesting comments on the advantages of
all ?)
Plus, is a false package a part of another package that can be found
with a tool such as apt-file for example ?
Thanks for all answers on these particular details.
Best greetings, J.Markoll.
