I'm having an issue with email generated from a website contact form. The email is being sent from the website via php. The issue is that the email address that it is being sent to is a domain/website that is also on cpanel. It is trying to deliver it to a local account, but the email is acutally on a third party system outside of cpanel. Does anyone know anyway for exim to not try and deliver locally?

whether our webhost has their configuration messed up, or if this is not genuinely possible with cpanel + exim + shared hosting.
Our email server is hosted with the web host, and what we want to do is to not allow certain users to be able to receive (And send) outgoing email to non-local domains e.g. they should only be able send and receive within our hosted domain, @mydomain.com .
Now, we've tried doing this using cpanel's user level filters and have setup the following:
Rules:
If Field To does not contain @mydomain.com OR
If Field From does not contain @mydomain.com
Action:
Fail with message.
We've tested these filters using combinations and they seem to be working as far as we can see on cpanel (it has the filter testing feature)
Now this works for people sending emails into our domain e.g. someone from hotmail tries sending emails to a user, and it bounces back.
But people from inside the domain can send emails to other domains even when they give valid results on the cpanel filter tester.
One of my clients has 2 accounts:
- foo.com, with a mail account info@foo.com.
- bar.com, with domain forwarding to foo.com.
Sending an email message to info@foo.com works.
Sending an email message to info@bar.com doesn't work. When using the ZoneEdit SMTP test utility I get the following error message:
Code:
> RCPT TO:<info@bar.com>
< 550 5.1.1 User unknown: info@bar.com
I checked "/etc/vdomainaliases/bar.com" and "/etc/localdomains", they are configured properly.
Any suggestions?
i have a vps but there is too much process called mailnull
after that the data centre closed my server for being sent spam
so how i can catch the user sending spam with mailnull?
i have run exim -qff from SSH then i got below error let me know what to do
Code:
root@web [~]# exim -qff
sda7: write failed, user block limit reached.
sda7: write failed, user block limit reached.
sda7: write failed, user block limit reached.
I thought I knew enough about my .htaccess stuff to do this, but I can't seem to work it out. What I want to do is if a user visits domain.com/folder, we check to see if the folder exists. If so, show as normal (IE domain.com/support)
If a user visits domain.com/dynamicusername (dynamicusername is not a physical folder), redirect to dynamicusername.domain.com
How do you get Exim to rewrite/remove
Received: from ip.isp.com ([123.123.123.123])
by mx.myhost.net with esmtpa (Exim 4.69)
I'm trying to avoid the error
Received-SPF: softfail (google.com: domain of transitioning me@myhost.net does not designate 123.123.123.123 as permitted sender) client-ip=123.123.123.123;
Basically, any email thats sent through myhost.net should look like it was sent directly.
I am having issues in receieving emails. For some reason, the rbl lists I had setup are causing the server to reject emails (retry - timeout). So, I need to take this rbl list completely. How can I do that? exim.conf is locked and using the advanced editor is no fun even though I tried it putting the dnslists without the rbl causing the problem.

View 5 Replies View RelatedI seem to be experiencing some difficulty adding SPF records via "Edit DNS Zone". When adding these records and checking them with several SPF record checkers, it always reports a record such as the following:
“v=spf1
Which turns out to be invalid, and definitely not the record I had specified. The record I specified looks like the following:
"v=spf1 a mx ip4:XXX.XXX.XXX.XXX ~all"
XXX.XXX.XXX.XXX being a valid IP, of course.
Is there known issues when adding these types of records via WHM?
And to make it clear, I have added these records as TXT type, with and without the quotes.
Wondered if anyone out there would like to share their experience, if any, of setting up cpanel to work with domainkeys via exim.
Hopefully anyone reading this thread will know by now what domainkeys are and how it affects the delivering of email to most major email providers inboxes rather than spam/bulk folders.
antispam.yahoo.com/domainkeys
The domainkeys support for exim is now in the 'experimental' phase:
duncanthrax.net/exim-experimental/
(page allegedly updated on 30th Oct, 06)
However cpanel themselves seem to be dragging their feet a little with implementing it:
bugzilla.cpanel.net/show_bug.cgi?id=4099
This is understandable considering support for domainkeys is not yet part of the main exim core code, and thus is likely to change. From what I've been reading elsewhere, re-compiling and upgrading exim is not advisable with cpanel.
My knowledge of exim (and cpanel TBH) is limited however, and I was wondering what might be the implications of *ahem* hacking it a little in order to enable domainkeys.
SPF records alone just don't seem to cut it anymore.
change some variables in exim.conf so that they will not be modified next time cPanel will update exim.
Basically I need to modify this:
smtp_banner and rfc1413_query_timeout.
more specific filtering options in cpanel exactly:
if header from contains 'example' and also header from contains 'example2' then discard
in cpanel it just has one word or phrase i need the filter to check for 2 words in any order in the from field
I found a handful of howto's for dspam, but none of them catered for exim with virtual users. After hunting around, I eventually have it working on a cPanel server, with user authentication for mail users.
My setup:
dspam version 3.6.8, using mysql driver.
exim version 4.
mysql 4.1
CentOS (2.6.9-023stab033.9-enterprise)
cPanel / WHM - latest RELEASE version.
Download the source, configure and compile:
Code:
# cd /usr/local/src
# wget http://dspam.nuclearelephant.com/sou...m-3.6.8.tar.gz
# tar -zxf dspam-3.6.8.tar.gz
# cd dspam-3.6.8
Configure, replacing user/groups with your web-server user (web / apache / nobody), and use your mysql-include / library paths (will need mysql-devel on rh based systems).
Code:
# ./configure --prefix=/opt/dspam-3.6.8 --with-local-delivery-agent=/usr/sbin/exim --with-storage-driver=mysql_drv --with-userdir=/var/spool/mail/dspam --with-userdir-owner=nobody --with-userdir-group=nobody --with-dspam-mode=none --with-dspam-owner=nobody --with-dspam-group=nobody --enable-whitelist --enable-spam-delivery --enable-alternative-bayesian --disable-dependency-tracking --enable-virtual-users --with-mysql-includes=/usr/include/mysql --with-mysql-libraries=/usr/lib/mysql/ --with-dspam-home=/opt/dspam-3.6.8/var/dspam
# make && make install
Set up mysql
Code:
# mysqladmin -p create dspamdb
# mysql -p
>grant all privileges on dspamdb.* to dspamuser@localhost identified by dspampass;
>flush privileges;
>exit;
Create tables:
Code:
mysql -p dspamdb < /usr/local/src/dspam-3.6.8/src/tools.mysql_drv/mysql_objects_speed.sql
mysql -p dspamdb < /usr/local/src/dspam-3.6.8/src/tools.mysql_drv/virtual_users.sql
Link dspam in opt for easy versioning:
Code:
ln -s dspam-3.6.8 /opt/dspam
Copy the web interface files to a web directory:
Code:
# cp webui/cgi-bin /opt/dspam -r
# cp webui/htdocs /opt/dspam/
This next step is required for pop3 authentication.
Install perl module Apache::AuthPOP3 - which does apache pop3 authorisation:
Code:
perl -MCPAN -e shell
install Apache::AuthPOP3
Next, apache will need mod_perl installed - WHM -> Apache Update will allow you to enable the perl module (I am running it alongside php with no issues).
Then in /usr/local/apache/conf/httpd.conf:
Code:
ScriptAlias /dspam/ /opt/dspam/cgi-bin/
Alias /dspam_files/ /opt/dspam/htdocs/
<Directory /opt/dspam/cgi-bin>
Options None
AllowOverride AuthConfig
Order allow,deny
Allow from all
</Directory>
Create .htaccess in /opt/dspam/cgi-bin as follows:
Code:
AuthName "Dspam"
AuthType Basic
PerlAuthenHandler Apache::AuthPOP3
PerlSetVar MailHost localhost
Require valid-user
#PerlSetVar UserMap pop3user1=>realname1,pop3user2=>realname2
#Require user pop3user1 pop3user2 pop3user3 pop3user4
there are 2 commented parameters you can set when using POP3 auth - sure its pretty self-explanatory.
Set up admin user (the admin_user must be able to authenticate as a pop user):
Code:
#echo "admin_user" >> /opt/dspam/cgi-bin/admins
Create a queuesize script for web user - so dspam can determine how many messages in the queue.
Code:
vi /usr/local/bin/eximqsize
#!/bin/sh
/usr/bin/find /var/spool/exim/input/ -type f | wc -l | cut -d" " -f1-
##EOF
# chmod 4755 /usr/local/bin/eximqsize
# chown nobody /usr/local/bin/eximqsize
Configure web ui, edit /opt/dspam/cgi-bin/configure.pl:
Code:
$CONFIG{'MAIL_QUEUE'} = "/usr/local/bin/eximqsize";
$CONFIG{'WEB_ROOT'} = "/dspam_files";
$CONFIG{'LOCAL_DOMAIN'} = "FQDN"; #your servers fully qualified domain name - e.g. host.yourdomain.com
Next, set the default preferences for the system (you need /opt/dspam/bin in your path if you copy and paste this...):
Code:
dspam_admin ch pref default trainingMode TEFT
dspam_admin ch pref default spamAction quarantine
dspam_admin ch pref default spamSubject "[SPAM]"
dspam_admin ch pref default enableWhitelist on
dspam_admin ch pref default showFactors off
Permissions:
I would suggest reading the README over dspam to get a full understanding of the permissions required for running of dspam. My permissions were:
Code:
# chown nobody:mail /opt/dspam/var/dspam -R
# chown nobody:mail /opt/dspam/etc/ -R
Edit dspam.conf (in /opt/dspam/etc/. I have only listed the parameters I changed here...):
Code:
TrustedDeliveryAgent "/usr/sbin/exim -oMr spam-scanned"
Trust: root
Trust: mail
Trust: nobody / httpd #choose 1 - what ever your webserver runs as - `ps axu | grep httpd` to find out
#Use the same details as you did for the "grant all privileges on...." statement in mysql.
MySQLServer /var/lib/mysql/mysql.sock
MySQLPort
MySQLUser dspamuser
MySQLPass dspampass
MySQLDb dspamdb
MySQLCompress true
MySQLVirtualTable dspam_virtual_uids
MySQLVirtualUIDField uid
MySQLVirtualUsernameField username
Almost there....
Confirm that mysql is configure to listen on a socket in /etc/my.cnf (or whereever your config file is):
Code:
# cat /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
Now the final step - exim configuration. This is the part that took the longest, hopefully it works for you. Just as I read in the howto's I used for this, please please please dont just copy and paste - you stand a good chance of breaking your mail server if you make changes without understanding. Be warned.
My config file is /etc/exim.conf. This should be edited using the WHM -> Exim Configuration Editor -> Advanced.
Code:
#Routers - Add these in the box before virtual_user delivery / user delivery router).
dspam_router:
no_verify
#uncomment the next line to disable dspam for virtual users.
# check_local_user

If you have set up authentication correctly as well, then you should be able to open [url] and log in - if you add your login details to the "admins" file, you can configure defaults, etc. It also allows ALL users (with 1 user being an email account) to log in, using www.yourclientsdomain.com/dspam/dspam.cgi
This will not work with suexec enabled!! This is because dspam needs specific permissions, and it is expecting user nobody to access it. If suexec is enabled, you will need to use the default host, and NOT virtual hosts (and even this may not work - testing still required).
Watch exim_mainlog after this - you should pick up what transports and routers are being used.
Dspam can really hammer a system - mysql, cpu and memory usage will go up a bit, especially on busy production servers. Monitor your servers performance.
Other settings: add /opt/dspam/man to MANPATH in /etc/man.config or move dspam man directory to an existing man directory.
[ADDED]
This dspam.cgi hack will do a lookup in the cpanel config file to find the domain for any username without a domain, and append it on match (or leave just the username part if nothing is found). This requires unsecuring your system a bit - your http user will need to be able to read /etc/trueuserdomains (either chmod 644 or chown nobody):
Code:
#add this just after $CURRENT_USER is set.
if ($CURRENT_USER !~ /@.+./) {
open(TUD, "</etc/trueuserdomains");
while(<TUD>) {
my ($domain, $user) = split(/:/,$_);
chomp($user);
$user =~ s/^s*//g;
if ($user eq $CURRENT_USER) {
$CURRENT_USER = $CURRENT_USER . "@$domain";
}
}
close(TUD);
}
That should do it
dspam will allow all messages through by default, and will require some training. With this config, users can train using email commands - all they need to do is forward any spam that hits their mailbox to spam-emailaddress@domain.com (their own email address with spam- prepended). Unfortunately this does not allow handling of false positives if you are using a "quarantine" policy instead of subject. the web interface comes in handy for this.
I am busy testing a combination of dspam with assp, which seems to be working well - I especially like the greylisting feature of assp and ProtectionBox... Will add to this howto when testing is finish.
We are having trouble with disk space on some of our shared hosting servers and we are wondering if anyone have a script to clean e-mails from exim not checked in the last 60 days ?
View 1 Replies View RelatedAre there others that are having a problem with exim getting slammed with the max allowed connections after updating to cpanel 11?
I have upgraded perl to 5.8.8 and upgraded cpanel. Now, all day yesterday, last night, and now.. pstree is showing exim maxed out.
Clients are complaining that they can't send email due to the "too many connections" error.
I have bumped up the max to 300 for now to hopefully get more clients able to send, but it is quickly working its way over 200 as I type this.
I have tried every setting in the exim configuration editor, on and off, I have a data center techs working on it since yesterday...
we have a freebsd/cpanel box what seems to be trouble prone combination, specially for exim.
After cpanel upgrade, exim simple has stopped. Somehow I managed receiving on this way:
# /etc/init.d/exim start
/libexec/ld-elf.so.1: Shared object "libperl.so" not found, required by "sendmail"
I checked which perl version is running: perl -v
This is perl, v5.10.0 built for i386-freebsd-64int
then applied:
unix1# ln -s /usr/local/lib/perl5/5.10.*/mach/CORE/libperl.so /usr/local/lib
unix1# /etc/init.d/exim start
exim exim antirelaydunix1#
unix1#
but this solved only half of a problem, now we can receive e-mails, but not send them, what is really frustrating.
Here is the error which cpanel sends on each 5 min:
exim failed @ Fri May 1 16:06:15 2009. A restart was attempted automatically.

Does anyone know if it is possible to implement DKIM (DomainKeys Identified Mail) on a Linux server that uses cPanel/Exim? I am interested in getting this implemented but not sure how, or if it's even possible yet on my setup.
