mail send and seen as spam

Hello,

I am a new user to qmail and made the installation procedure twice already with qmail handbook. Everything seems to technically work fine (I use qmail only as a relay for the moment). I use dnscache from djbdns, daemontools, ucspi server and net-qmail package. The only problem is when I tried different type of mail (customizing the /control files) I always finish with mail in spam box. I have tested gmail adress, yahoo adress and hotmail adress and I always get my mail there in the spam box.
I guess there is something - may be - obvious that is checked by all these servers but cannot figured out what it is that let them think I am a spamer.
If there is any information people in this list may need to help I can provide it of course, like a piece of source mail for instance.

If you have an idea it would help.

thanks

You've not given us details of your particular setup/circumstances beyond
reference to the qmail handbook (I assume you mean Dave Sill's book). However
my first guess would be that your qmail server is setup with a dynamic IP
address, where users would normally be expected to use their upstream ISP's
email server for their outgoing SMTP. You may be bypassing that and therefore
considered suspicious. Check your IP address at SpamHaus for example,
http://www.spamhaus.org/lookup.lasso

If that is the case, one solution may be to setup your ISP's mail server for
all remotely-destined addresses in /var/qmail/control/smtproutes (see man page
for qmail-remote).

Let us know how you get on.

cheers,

Andrew.

Is your server operating in a dinamic ip netblock range, aka residential
netblock? Does your server ip have reverse dns? Did you inherit that IP
address from a former spammer/netbot host?
There are a lot of variables that influence those decisions, and
unfortunately, not all are in our immediate power to change.

Sorry, but BLAH!
99.99% of all broadband customers dont't need a static IP address.
If you want to run a mailserver, go ahead and get a contract with a
static IP address. All else is bad practice, laziness, and poor planning
on your side.
ISPs should block port 25 outgoing by default. Customers who want
to make outgoing connections to port 25 should be able to enable this
via the customer interface. Would cut down on spam some magnitudes and
also on DNS traffic.

> And we need to get on with IPv6.

Agreed.
But everyone having a static IP address on their home desktops gives all
trackers and user profile creators wet dreams (multiple per night).
And it doesn't change the spam problem in any way.

Come on, stop whining.
I have my own list with about 1000 domains right now and I reject from hosts
without revDNS.
I block more than 99% of all messages and the only two messages that were false
positives in the last 5 years were a promotion newsletter from the clueless
people at Sony (mailserver has no revDNS) and one from a forum system which
the admin had emergency moved to a new server due to a breakin' and which had no
reverse DNS, also.
I know of no legit mail blocked by my wildcard domain block.

So you say I should install some CPU hogging bullshit content scanners and scan
some 1000 mails a day just for the option of maybe receiving a message from a
whiner behind a dynamic domain? All this for 1 in 1,000,000 users?
No, sorry but NO.
I am not going to pay for you being lazy, using bad practice and having poor
planning.

My server at home is also on a dynamic range I block, and injects its
mails via submission to my server.

It surely is not the fault of the users if some of the programs they
run are vulnerable. But IT IS the fault of the users to not (automatically)
upgrade the system, run an uptodate virus scanner (if they insist on using
windows) and to be so fscking stupid/horny/greedy to click on any damn link
or attachment they get send.
And yes, updating is more work in windows, but there are tools like Secunia
PSI which I always recommend to anyone asking (it is free and no I am not
related to Secunia in any way).
