Exim: Is there away to block command when someone telnets to exim's port? Email won't send out unless they authenticate, but if there a way to total block them from typing all together, but still allow the server to receive email? IE, to block this:

I installed CentOS 3 and during the installation, I configured the disks using 'software RAID'. Then I installed my /data partion on /dev/md0. Everything seemed fine however I install a extremely bare installation of CentOS 5.3. I don't select any packages during the install process which includes anything under the 'base' package software selection. I then noticed that because I configured my system with 'software RAID', it found 'mdadm' as a dependency package and installed 'mdadm' however this also then grabbed 'exim-mta' package so now I have 1/2 a mail server installed simply because I have software RAID on my box. I am not permitted to have anything beyond 'Postfix' MTA on my LAN. I don't want Postfix any ways on this machine so is there a way I can install CentOS 5.3 cleanly w/o packages I don't want or need? I am sure I can 'yum remove exim' and that in turn will remove 'exim & mdadm' from my machine however I would like to start fresh.

What's interesting is that in some places the correct domain is given, but the return-path and the envelope-from are set incorrectly. I should add a few things: this machine is used only to send email newsletters and for email generated by the websites; staff email is handled elsewhere the output of hostname is myhost the output of hostname -f is myhost.mydomain.net when I ran dpkg-reconfigure exim4-config, I set the system mail name to "localhost" so as to "'qualify' mail addresses without a domain name." I have a feeling this is the source of my problem, but when I set this to mydomain.net, I ran into another problem: I essentially disabled local mail. Messages to root (e.g., the results of cron jobs) would show up in my logs as root@mydomain.net. I want local mail to follow the rules set forth in /etc/aliases, not be converted to local-account@mydomain.net.
It's been awhile since last dealt with Debian.
I'm setting up mail server on Debian 5.04
So I need exim4-daemon-heavy, I removed exim4-daemon-light and can't find heavy, in fact can't find any exim package.
I have Debian and I see that exim is installed on it. I want to make my own home mail server, but with postfix. Do I have to remove exim first and then install potfix or what?

View 1 Replies View RelatedI've setup Exim4 as an MTA on my VM which has a static IP. I've pointed the MX records both idential to this static IP. I can send out via command line on the VM using Exim commands and receive the mail in my home account no problem, it also displays the correct from address ie rich@mydomain.co.uk
So I'm not sure what's going on with receiving the mail. If I send a mail from my home email to rich@mydomain.co.uk (not real address), I don't get a bounce or anything, it just goes out never to be seen again.
We moved over from Cpanel using Exim. I was wondering if anyone knew of way to convert the mail so when a user logs in they get to all their mail in their folders. I notice exim has a ton of folders while postfix creates files that act like folders which contain all the emails. I sent up 1 of the emails into the our mail folder that was created by Exim and it can be Subscribed to in Outlook with imap but the emails inside doesn't show up. They both appear as text files so I don't know what the difference is.

After logging into a fresh Debian 5.0 (lenny) install from a VPS (virtual private server) provider, I run 'apt-get update' and then 'apt-get upgrade' in attempt to get all the security updates, assuming that's what said commands do. Along the way exim (exim4) and possibly other programs (not confirmed) gets installed and is setup to run on bootup...despite it not being installed previously. Why is this? I would expect that either 1) previously uninstalled pkgs are not installed with the 'upgrade," or 2) if 'upgrade' essentially performing a "install everything that's not already installed" maneuver, I wonder why it's not installing a LOT more packages (then just the view I see installed on my system during the 'upgrade.')
Separately: can someone confirm an 'apt-get update' followed by apt-get upgrade' on a fresh Debian 5.0 install system will basically upgrade to 5.0.8 ("current rev level" for lenny)?
I have exim setup on squeeze to run as an "internet site". Outgoing mail works fine but it seems to just ignore incoming smtp requests on port 25. I can see the incoming connection via tcpdump but exim doesn't seem to talk. If I connect via telnet it rather quickly says connection refused. Is there something additional I need in the Exim conf?

I run OSX on my everyday computer so this is not me sending out stuff since the above mail says Microsoft Outlook express has sent it (?) Running a Debian Squeeze server. And I really dont get any other spam due to exim4u setup and spamassasin.
Install One :
Installed Debian Squeeze onto my laptop using the netinst cd. During installation, I did not have access to the internet and installed "Standard System" during tasksel.
Install Two :
Installed Debian Sqeeze onto my desktop using the same netinst cd. However, this time I had connected the desktop to my router during installation. Similary installed "Standard System".
Both system later installed with KDE and working fine. Noticed that immediate after installation of the "Standard System", my desktop had more files installed eg. the exim package. Why the extra packages (eg exim) are installed? Are they actually required?
Has anybody else seen this kind of attack? I see those messages on 2 exim mailservers. Looks as if someone sends a 50MB big mail header :S What is their goal except from increasing my traffic?

I have 3 ip address on my VPS and I need to change exim configuration to listen only on one ip address.
VPS have WHM and Cpanel installed.I changed in exim configuration interface to my ip.
My employer has started the process of certification with Return Path, and I've been roped in to setting up DKIM, SPF, SenderID etc. so that we are compliant with the certification requirements. Our current e-mail server is qmail, and I'm really not too keen on messing about with the configuration files there. As a safer alternative, I've decided to set up a smarthost relay that only does the DKIM signing. I tried and gave up on Postfix - struggled with understanding the configuration files - and eventually found Exim.
Now, I've got the relaying working perfectly so far. I am NOT running an open relay, my smarthost is configured to only accept SMTP connections from the existing mailserver, and not publicly accessible anyway. The problem I'm having is figuring out exactly where in exim's configuration file I am supposed to configure the DKIM signing options. I've read the official exim documentation and I'm fairly sure about the syntax, I just can't figure out where the options go.
I recently built a mail server with Slackware/Sendmail and basically all works. Mail comes in and goes out. The problem I have is 3 email addresses cannot be sent to from this server. The remote ends are 3 different servers but all run Exim 4.69. I have logged the server exchange and this is what I get: (names have been changed to protect the innocent!!)

Exim user can get owned by a remote exploit [URL].. I was running Exim 4.63 5.el5_5.1 on CentOS 5.5 x86_64 and my Exim user got owned by that exploit.
Now I ran yum update and exim updated to 4.63 5.el5_5.2 I cannot find anywhere if this updated fixes the exploit.
I have a fairly standard Exim setup for inbound and outbound mail. Recently our development team has put together a PHP app that allows us to send out bulk mails to our clients. The PHP app uses standard PEAR libraries to initiate an SMTP connection to localhost (application and mail server are on the same box). The idea here is that the application will send out roughly 10'000 emails in a very short time period (60 seconds or so) which Exim will then hold in its queue for delivery.
The problem comes in where after about 50 emails, Exim stops accepting mail and loggs the following error in the exim_main.log file: SMTP command timeout on connection from localhost [127.0.0.1] Could it be that this is because Exim immediately starts delivering the mail and then stops accepting new incoming connections? I thought that increasing the SMTP limits may be the problem here, but even after setting new values in the exim.conf file to the following, I still get the same problem:
queue_run_max = 5000
smtp_accept_max = 5000
smtp_accept_queue = 5000
This begs two questions: How do I resolve this? What is the best way for configuring Exim to accept a huge amount of mail into the queue in a very short time period, but then gradually delivery it once it's all in the queue? I've seen some people run separate Exim daemons for incoming and outgoing mail; is this a good solution?
I have a nice little interface that generates an exim config file and a script on the server to check for changes. Unfort I cant find where to set the config file location.
E.G. I have my script generate the file to /etc/exim/exim4.conf (could be /usr/share/foo/bar.conf just as easily)
How can I point exim in the direction of that file?
I'm trying to follow the exim documentation to allow suffixes on mailboxes for all users. For example, if user@domain is a mailbox, I want all mail directed to user-*@domain to be delivered user@domain. I've got the split-config-files option and have edited /etc/exim4/conf.d/router/600 to include local_part_suffix lines as follows:

View 1 Replies View Relatedafter installing Debian, I typed the command:
Quote:

to avoid automatic start of this mail server (I use qmail). After several months, I did a reboot and exim is started! Looking at the history, I found this command:
Quote: dpkg-reconfigure exim4-config
Maybe this command has restored the init script of exim?

View 2 Replies View RelatedI'm in the process of starting a migration from an old postfix server to nice shiney new exim server however there are a few things i'm really not clear on and i'm hoping that some one here could point me in the correct direction. Okay the postfix server at the moment does the follwoing ( i'll try and keep this simple ):
* accepts incoming mail for users on multiple domains and puts the mail in the users mailbox ( external -> internal )
*accepts mail from users on multiple domains to pass on to the outside world ( internal -> external )
Obviously the POP and Imap functions are handled by other daemons.. I'd like to replicate this sort of setup on the new exim box, however the guides i can find only help with configuring the exim system for incoming mails ( external -> internal ) for multiple domains and i cant seem to find a guide that would indicate how to do both ( internal -> external and external -> internal ) on one box. I'm guessing i may have to do some sort of auth to get exim to accept and then handle the internal -> external side of things?
I haven't used Debian in 1 year or so and would like to know if there is any possible way to do a fresh installation of Debian Lenny or Squeeze (either or) and not install Exim? I get to the package selection section of the Debian Installer and I de-select "Desktop Environment" & "Standard System" so nothing is selected and it still be default installs Exim. Is there a way to omit this from the install?
