I have been thinking on this for a while now. Since logwatch can send a mail
to another server and that server DOES not mark it as spam, that presents a
logic issue. Now, the other server does not have as new a spam assassin as
the new, so it is hard to check it that way.
So I 'replied' to the logwatch file and sent it to a known user, back to the
new server. It never arrived.
>From that I know a 100% spam assassin is taking it, not based on local
usernames, or any sendmail settings. I had originally thought that because
'logwatch' was not a sender that would be an issue.
I like the 'from ip' whitelist, but is not that spoofable too? I imagine
making it both 'logwatch and from this IP' might be better.
In logwatch there is a setting to say who the mail is from, right now it
says 'logwatch' but I could always add some long goobledy gook as 'from'
like
"alkjfpolp3534j4f9logwatchsd9f9se9sdf9s99fwe"
And then whitelist that, make it like 40 characters or whatever.
I can understand why spamassassin cannot tell it is from a local user or
have the ability to just auto whitelist stuff from a local user....but I can
forsee problems with interwebsite mails and even things like mailing lists
on the server without properly thinking this through.
Never thought this would be an issue, but at least I know how to make it
work...sorta.
