Resolving DomainKeys Install Issue
Aug 5, 2008I 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:

View 1 Replies View RelatedSASL Authentication For Mail Server (Sendmail/Postfix)
Mar 18, 2007I recently moved to virtual dedicated hosting for my website, mainly because I wanted a better mail server to work with to manage a mailing list.
I have a few PHP software scripts for different things: managing affiliates and email marketing.
I want to send mail using both of those via SMTP on my new server. They both have a place to type in the host and username/password.
The problem I am noticing is SASL Authentication. They attempt to connect to the host without any trouble. However, the affiliate software fails SASL Authentication every time I try to send an email or test the email system.
Email marketing software connects when I manually send a campaign. However, users are supposed to immediately receive a confirmation mail upon opting in. In this case, it shows up as an attempt in the mail log, but it fails SASL Authentication. I don't know if it's a problem with the software or not, since it attempts to connect but fails, yet connects successfully in other cases.
My question is this: Is there another way around this? I've contacted my host to double check on the appropriate username/password to pass authentication. I will also be contacting the software developers after I receive an answer.
But if nothing comes of it, is there any way around it? Is there a place where I can have it automatically authenticate if the email is coming from a certain user, or if the attempt is being made from the same server (everything sits on the same server, I use localhost in the software to connect to the mail server). Since I am the only person who has access to the server and uses it, it seems safe to automatically authenticate if the request is being asked by the server itself...
I'm just looking for other alternatives if the software does indeed have a problem and I cannot figure it out.
Keep in mind I am very new to all this server and root access. Just a few days ago I was on a shared hosting plan, so I didn't have any access to anything. With that in mind, I know very little about mail servers, although I've been learning more over the past few days. I only stumbled upon the mail logs on my server recently by browsing files in the control panel (I'm not familiar with SSH, although I do have access to it)
Plesk 12.x / Linux :: Postfix / Sendmail - Senderdomain Is Not Registered In Panel
May 1, 2015I have a Plesk installation with Commandline access. Also on this server is a Request tracker installation. (The reason for the commandline access) CentOs 6 Server.
All installations are up to date, but this actually broke my installation after the last Plesk Upgrade.
At the last Plesk upgrade, my Request Tracker installation can no longer use sendmail to send email directly from the server.
The errors I am getting are:

Plesk 12.x / Linux :: Postfix - Mails Sent Through Sendmail Binary Blocked Because Of Wrong HELO
Jun 23, 2014My server is using Centos 6.5... I updated from Plesk 11.5 to 12 last week and postfix to 2.8.17.
Since then, all mails sent using the sendmail binary (notifications, mail forwards...) are being rejected with a wrong HELO hostname: localhost.
It seems that sendmail is using locahost as a HELO tag which is not accepted. Here is the following error:

DKIM/DomainKeys And You
Jul 5, 2009how 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.

Cpanel > Exim > Domainkeys
Feb 21, 2007Wondered 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.
Plesk 12.x / Windows :: After Migration Domainkeys Header Not Added To Sent Mails?
Feb 27, 2015I 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?

PHP Sendmail
Jul 31, 2007My website is running of a windows server, and so doesn't let PHP sendmail work .
I only remembered this recently, and now know why I have been loosing out on clients.
Is there a work around to this? i.e possibly some sort of script that emulates the linux sendmail? Note: I don't have access to the windows server config, it is a shared hosting account.
As I was on windows and hated my hosts spam protection (took almost 3 hours for the spam filter to confirm safety of emails from gmail servers) I moved the email system to an external company, that now manages my pop3/smtp etc. (not sure if this makes any difference - but may as well explain it just incase)

View 6 Replies View RelatedSendmail Tightening
Mar 19, 2009I haven't used Sendmail in a while and would like to clarify a specific setup.
Suppose we have a box hosting a handful of clients, thus it is a Shared setup.
Suppose we have Sendmail sendmail-8.13.1-3.3.el4 on a CentOS 4.7 Final installed with 0 extra configuration other than the default one.
Such setup allows on to relay via the localhost method through php/cgi scripts or even manually through sendmail binary.
Ideal setup would be one where I would have the ability to specify into a file, the usernames allowed to relay email. E.g
if /etc/passwd contains
user1
user2
user3
user3
baduser
user6
spaminguser
than ideally I'd like to pick 'baduser' + 'spaminguser' and disallow them the ability to relay through the localhost.
I should not know anything about their domains or where they are sending.
A general directory setup might be
/home/user1/domain1.com
/home/user1/domain2.com
/home/user1/domain3.com
/home/user2/domain.com
/home/user2/sub.domain.com
etc.

Sendmail Redirect
Jun 16, 2008A spammer has sent a ton of users a phishing email requesting the users password...
I work for a regional ISP, and we deal with alot of elderly people who would probably send him a response with a password... I looked over the mail log and one person did respond back to him...
Basically... I want to do like... a virtusertable entry that forwards any email sent to HIM... to ME...
so basically... his email is for instance: phishingspammer@gmail.com
I want to do something like this in the virtusertable (I understand it probably cannot be done thru the virtusertable):
phishingspammer@gmail.com goodguy@regionalisp.com
This way I can alert the people who DO try to send him emails that the email was stopped and to never respond with a password.
