Qmail and Spamassassin - some emails are received, and some not
 
Hello,

On server I have installed Qmail server.

Problem I have is that emails from some sources (like Gmail, Yahoo, HotMail) are received, but some from other domain are not. When I say "other" I mean domains hosted on server like Bluehost (I have several domains hosted there).

I think that Spamassassin is something that causing problem, so I tried to edit file /etc/mail/spamassassin/local.cf, by adding a line

Code:

whitelist_from *@MYDOMAIN.com
... but still no luck, still not receiving emails from "mydomain.com".

What I also can say is that few hours ago I upgraded SquirrelMail webmail client, because it was creating some errors when sending emails. Before upgrade, there was no problem receiving emails from "mydomain.com" (but I also know that there where same problems with some other domains). So something blocks incoming emails.

Can you point me where to check and how can I solve this problem?

Thank you in advance!

I turn off qmail-spam, but it's still the same...


Please help...

And one more update!

I received all of the emails, but few hours late.

Can you give me some idea why it takes so long?

One more update on this:

I can receive emails, but not from all of the senders.

What I did last is that in file /etc/tcprules.d/tcp.smtp I added a line:
Code:

:allow,RELAYCLIENT=""

.. and (of course) compile the rules into the cdb with :

Code:

qmailctl cdb

Now I can receive emails from some of senders that I was not able before, but not from all of them...

In log files I cannot find anything strange.

Can you tell me where to look for more?


Thank you in advance!

Hi, first of all your tcprules will allow remote clients to use your MTA as an open relay. If you don't want to be banned by the block-lists you should fix this. Be aware that
Code:

RELAYCLIENT=""
should be assigned only to IPs that are allowed to send *outgoing* emails, not to allow them to deliver messages to your MTA. Thus, if you just want to receive messages from the internet, it is sufficient to have

Code:

:allow
in your tcprules. For a quick guide on tcprules you can take a look at this page I wrote http://notes.sagredo.eu/node/129

Concerning the main issue, can you post your tcprules, qmail-smtp/run files?
Do you have any rbl active or any other filter/wrapper active? First of all I would disable rblsmtpd and look at spamd.log to see if spamassassin is really denying some IP.
