NEED HELP with my qmail server

[marcosacramento]

My server keeps accepting mail for sending from invalid users from my domains.
I've enabled smtp-auth but nothing happens. Also made my whitelist 127.0.0.1/32. The same result.
I also have a message like this in my queue to root very often:
/bin/bash: line 1: /usr/bin/qmail_check: No such file or directory

I don't know what to do.
My service provider limits my queue to 1000 a day and i'm getting there by 8:00AM.
Then it doesn't deliver more mail.

Also tryed abuse.net relay test and it says that it appears to be open relay on last test.

Please help me.

Thanks in advance,

Marco Sacramento

No one knows what the problem is?
Please answer.
I'm desperate.

Thanks.

Can you give an example? Your question is a bit unclear.

 

[marcosacramento]

I get a lot of messages from invalid users from my domains (someone@mydomain.com) to several addresses.
I gess that some of those addresses don't exist also and i get bounced, bus as the user doesn't exist, my server bounces it again.
That's what i think is happening.

This is the report i get on abuse.net.
(I switched the ip and domain names)

By the way, most of the messages are for aol users.

Make sure each domain is setup to "reject", not "bounce" the mail for invalid users. You will have to drill into each domain and adjust the mail settings. For example, the output from domain_pref.sh should list the setting "Mail to nonexistant user" as reject.

# /usr/local/psa/bin/domain_pref.sh -i abc.com
Domain 'abc.com' limits:
Disk space: Unlimited
Maximum amount of traffic: Unlimited
Maximum number of mailboxes: Unlimited
Set the mailbox quota: Unlimited
Maximum number of mail redirects: Unlimited
Maximum number of mail groups: Unlimited
Maximum number of mail autoresponders: Unlimited
Maximum number of web users: Unlimited
Maximum number of databases: Unlimited
Maximum number of mailing lists: Unlimited
Maximum number of Java applications: Unlimited
Maximum number of subdomains: Unlimited
Validity period: Unlimited
Mail to nonexistent user: 'reject'
WWW: true
WebMail: true
Allow the web users scripting: false
Retain traffic statistics: false
Domain status: Domain is active.
SUCCESS: Gathering information for 'abc.com' complete.

 

[marcosacramento]

Thank you for your reply, but i have already verified that.
All domains are set to reject.

Regards

How about posting those examples then? (Not the abuse.net relay test!!!)

 

[marcosacramento]

what would you consider examples?
maillog?

Here it goes a sample:

Don't know if that's what you asked for.
Strange thing UID 48 is apache...

Regards.

 

[wagnerch]

grep the log file for "33898620" and post that. I would bet that your messages are being submitted locally.

also post the output of "ps -fu apache".

 

[marcosacramento]

The output of "ps -fu apache" is:

UID PID PPID C STIME TTY TIME CMD
apache 4416 20480 0 12:08 ? 00:00:16 /usr/sbin/httpd
apache 32643 20480 0 13:35 ? 00:00:16 /usr/sbin/httpd
apache 14897 20480 0 14:57 ? 00:00:11 /usr/sbin/httpd
apache 17153 20480 0 14:57 ? 00:00:12 /usr/sbin/httpd
apache 11745 20480 0 21:21 ? 00:00:00 /usr/sbin/httpd


The grep of the log file is attached because it's too big to post.
(you can get it in http://www.portadigital.com/33898620.log)

Regards.

 

[wagnerch]

Your messages are definately being submitted localling:

Sep 1 04:09:50 netregistos qmail: 1157080190.013012 info msg 33898620: bytes 23128 from <anonymous@www.netregistos.com> qp 6016 uid 48

Messages from remote typically have a uid of qmaild (2020 on my box), uid 48 is probably apache.

Is netregistos.com one of your domains? If it is then I would suggest running the following command and see if you can correlate it to a specific web form:

grep ":04:09:50 " /home/httpd/vhosts/netregistos.com/statistics/logs/access_log

 

[marcosacramento]

I think i found the problem.
I ran:
cat /home/httpd/vhosts/*/statistics/logs/access_log | grep "04:09:"
210.220.216.34 - - [01/Sep/2006:04:09:48 +0100] "POST /formacao/pre_inscricao.php HTTP/1.1" 302 - "http://www.oneofmydomains.pt/" "-"

What do you think?

Regards.

 

[wagnerch]

It looks like that POST got a 302 error (a redirect), I would atleast take a look at it and see what is going on there. Perhaps there is another entry a few seconds later?

The first recipient on the e-mail is "formacao@infeira.pt" (which happens to be the same directory as the PHP page), which makes it suspicious.

Take a look at .htaccess files, etc.

 

[marcosacramento]

i think that the first recipient is that one, because that is a php script to send a message to the email.

It´s "forms to go 2.5" script.
