Hi folks!
I am pretty new to this forum and linux server administration. This is my question:
I am running a Debian server which got somehow compromised using vulnerabilities of unupdated versions of portmap and exim4.
Somebody used the server to send spam. exim4 was connecting to irc, portmap was mapping hundreds of ports and some evil perl scripts were causing drama.
i have installed the exim4 using aptitude install exim4
and configure with dpgk-reconfigure exim4-config
this is my /etc/exim4/update-exim4.conf.conf file:
dc_eximconfig_configtype='internet'
dc_other_hostnames='midomain.com'
dc_local_interfaces='127.0.0.1 ; ::1'
dc_readhost=''
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost=''
CFILEMODE='644'
dc_use_split_config='false'
I'm trying to figure out the source of some failing email to root@ on an internet server. I don't know if it is anything to do with exim4, but that's the MTA.
I can see the logs of the attempts with the external server in /var/spool/exim4/msglog, and what looks like a log of messages received by exim4 in /var/spool/exim4/input.
i've got exim4 on ubuntu server and i-ve got a pool of 20 external IP's.
Is that possible to configure exim4 to use this ip-s rotating to send mail?
I think i could do this with iproute / iptables load balancing with "link stick" but i want to know if this is possible with exim4 internal configuration.
I only want to send email from my VPS through exim4.
When I run netstat -anltp | grep "LISTEN" the output is:
tcp 0 0 123.45.789.10:25 0.0.0.0:* LISTEN -
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN -
Does the fact that my public ip is listening on port 25 means that someone is sending mail also through my
Installed debian from DVD. And now I see exim4 is running owned by UID 107.
I'm trying to get rid of the version number that you see when you get an email sent from Exim.
Received: from user1 by site.org with local (Exim 4.72)
I'v tried editing smtp_banner in these two files
/etc/exim4/conf.d/main/02_exim4-config_options
/etc/exim4/exim4.conf.template
But deleting the version number from there, then reloading Exim's config doesn't work.
I send my test emails like s
(I posted this on Superuser but I realized that it was probably better handled here)
I've recently set up a development server at my job to test out certain features. I am setting up exim4 to be the MTA for the server. However, when I test and send emails to my account on the server, even though I have multiple entries in /etc/aliases it only sends to one of the email addresses.
i would like to send emails whenever a cronjob has completed, i read that this is possible with exim4.
in /etc/alias i added the line
myuser: mygmail@gmail.com
in /etc/exim4/update-exim4.conf.conf
i set dc_smarthost='smtp.myserver.ip::25
and in /etc/exim4/passwd.client i set
smtp.myserver.ip:login@my.domain:mypassword
my problem is that i can't see any login at my mailserver, and in the e
