My servers have issue when send email to yahoo. I found out something like my server have to use Domainkeys for send email to yahoo mail.
I'm using CentOS 5.1 64Bit, Cpanel 11.
recomplie exim with Domainkeys support?
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.
I ordered a new server and recomplied apache to upgrade apache to apache 2 and to install GD
GD is installed but all captcha images are blurry. Can anyone help?

how everyone else approaches DKIM and DomainKeys.
I'm starting to see a lot of implementations now and have recently started adding DKIM and DomainKeys verification to my outbound mail.
Two things strike me:
1) The number of DKIM users also adding DomainKeys
2) The number of DKIM and DomainKeys signed domains that remain in test mode. Example, Yahoo! and Amazon.
My questions:
Do you still use both DKIM and DomainKeys? If so, why?
Do you leave your domain in test mode? Or are you fully confident of your implementation?
Currently I support both, but dropping DomainKeys seems like the right thing to do, DKIM is the way forward, so can anyone tell me why I should still do DomainKeys? Is backward compatibility important?
Interested to hear others opinions.
Does any one know if plesk 8.6 / 9.0 supports DKIM
I have currently set up domainkeys on all outgoing email accounts but really need DKIM setting up
I am having a problem with the installation of DomainKeys on my server.
I have a dedicated server from Hosting Matters and I have DomainKeys installed for another domain on the same server.
The problem that i'm running into is that I have a domain that is an addon account of another (basically hosted within a sub-directory of another account).
When I install DomainKeys via the cPanel I get no errors. It "appears" to work fine HOWEVER when I check the headers in Yahoo I get the following:
Authentication-Results: mta215.mail.re2.yahoo.com from=paperboyllc.com; domainkeys=permerror (no key)
Received: from 63.247.138.128 (EHLO ws1.wpdnsgroup.com) (63.247.138.128)

h=Received:To:Subject:Date:From:X-Mailer:MIME-Version:Content-Type:Message-Id:X ...
I have both sendmail and postfix installed. Which Should I install?
DK-MILTER-1.0.0?
or DKFILTER?
I recently realized that domainkeys headers are not added to mail messages that are generated on our server. We are using MailEnable Enterprise 8.60 (upgraded on the Stardart edition, that is installed with Plesk).
I thought the problem could be related with this upgrade and created a new VM and tried that out. Installed Windows Server 2012 R2 Std, enabled DNS and IIS with ASP.NET versions, applied all updates, installed Plesk 12 and Upgraded to MailEnabled Enterprise. On the new server mails are going with the correct domainkeys headers.
Now I think that the problem was generated because of the Migration. On the old server Plesk 11.5 was installed and we didn't have any domainkeys issues. When we created our new server, with the same steps I wrote below, and migrated our backup to the new server, domainkeys headers weren't there anymore.
I couldn't find any documentation about this issue. Is there any commands to reset the settings related to domainkeys or may be it's a curruption in the psd database?
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.

2 exim process start using a lot of CPU (that's not 100%, but it's like 40% for one process and 35% for other) for hours...
but, as soon as I restart exim, that stops
so it's not a high mail load on server, nor anything like that
I even checked logs to see if it was on some kind of infinite loop (auto-auto-auto-auto-reply), etc, but can't find anything out of ordinary
anyone experiencing something similar?
I have a dedicated server with WHM installed on it, but recently I've been having problems with emails, specifically exim.
The main issue appears to be a huge number of exim processes all running at the same time. It pushes the server load higher and higher (and when I say high I mean over 100), and basically locks everything else up until I can get a command through to kill exim.
After a bit more investigation I found that the mail queue in WHM appears to be seperate to the one I can find with the exom -bpc command, and gets full of email sent to non existant domains or accounts. So my first theory is that at some point exim tries to deliver all of these at once and that causes the massive load spikes. I don't know if that's possible, or probable, but there isn't enough legitimate email coming into the server that there ought to be any issues.
i've read about how to control the mail q from exim, but that doesn't appear to make a different to the q shown in whm. Currently the server is being held up by a cron running every half hour to restart exim automatically, but at peak times this doesn't appear to be doing enough, and at one point yesterday exim had 400 running processes.
Obviously this is causing a few problems. I don't have the technical knowledge to diagnose or fix the problem past the guesswork i've already done, so i'd appreciate any suggestions
I have some clients who own large forums, and during usage Mass Mail CPU goes up to 100%. Is there any way to re-configure the exim so not to distrupt the CPU that much?

View 4 Replies View RelatedI'm trying to diagnose some server load spikes, and I've noticed that my exim log files are getting huge (5 gigs, plus 4 gzips at 1.7gigs)...my server status shows the gzips and greps on these log files putting my cpu load at 99.9%...how do i keep these from getting so huge and/or keep them from maxing out my server?
I'm running CentOS and cpanel...
In WHM > Server Status, it shows exim as:
exim (exim-4.63-1_cpanel_maildir)
I remember it used to show more stuff inside the (). Can you tell me what it shows on your server?
I recently switched over from Virtuozzo to WHM (on a vps), and was going through some of the different pages there. I noticed one page that displays the exim stats, similar to running it through the command line. Anyway there is one section I'm not entirely sure what it's referring to.

What makes it weird is that..
when i send email from hotmail to my servers account, i get email from hotmail, and, when i do reply on that email to @hotmail, email arrives @hotmail.
I am not actually a hosting provider but a client. I do have some technical knowledge about Exim, Sendmail etc and my host also co-operates with me so I thought of asking this question myself. My problem is with the RBL checks that my host's server performs even on authenticated SMTP connections. My ISP provides a IP to me which is being shared by many subscribers and gets blocked often. This causes a problem for me to use my mail client to send outgoing e-mail through my host's SMTP.
Suppose my hosted domain is "mydomain.com". Now when I use my e-mail client and send an e-mail using my hosts SMTP server (which requires due authentication) and give return-path (envelope sender) as "someone@mydomain.com", the e-mail passes through nicely. But when I use some other return path like "me@yahoo.com", I get a RBL block message after RCPT command. This should not happen as I am a paying member and I am correctly authenticating myself using the username & password of my hosted account.
My host uses Exim 4.63 so I just wanted to know whether there is a way to modify Exim ACL so that it doesn't perform RBL checks for authenticating users.
to run exim command line for delivery all emails in the queue
we need to use command as single:
exim -M xxxxxxx
BUT without <message id>
as
exim -q -M
but not work

I am sending out an email blast to about 30000 addresses when I leave. Because this is the down-time for our site, is it possible to temporarily give Exim more resources to help process? Or would this even be beneficial?
