similar to: DKIM mails from this mailing lists

I haven't learned a lot about DKIM yet, but I guess I'll need to implement it in the near future, at first for signing outgoing mail. I'm using exim as an MTA. I guess the standard exim 4.63 binary rpm from CentOS repos propably does not have DKIM support yet? Or does it, maybe? Provided the standard binary rpm does not provide this functionality, what would be the most decent

I created a client library to send emails for a webapp. When the client library makes a connection to the SMTP server, and then do NOT add Message-Id header, Message-ID (with a capital D) header is added, and the SMTP server adds a incorrect DKIM-Signature record 'h' part, invalidating the generated DKIM signature value. This causes outlook, yahoo, gmail and other email recipients

Hi, -- This message refers to the maillist itself rather than to dovecot software -- I have noticed that when I post to this list (only), I get DKIM Verification failure reports from: root at moncton.sidefx.com (e.g. for my last post: "DKIM failure report for job 4D27B5DC4E on mail.sidefx.com") root at mail.rmacd.com (e.g. for my last post: "DKIM failure report for job

I am trying to install dkim-milter-2.7.2 on a Centos 5.2 system and keep getting the following errors. I have very little experience in C programing so I am at a loss as how to proceed.

Hello mail admin, Currently the nut-upsdev mailing list mail is mostly getting marked as SPAM (or SPOOF) due to failed DKIM. DKIM is trying to verify mail headers signed by the original sender, but using the mailing list DKIM key (or lack thereof). This occurs because the DKIM mail authentication looks for a authentication key for the headers based on the HELO/ELHO user, but the message is DKIM

Hi Dear Community Friends, it is few days now, i am trying to figure out why DKIM is working / not working. Any assistance would be very much appreciable. Server IP is not blacklisted ever, MX, PTR SPF, DKIM records are available in DNS. why it is working at Gmail, why failing at Yahoo? Gmail dkim=pass header.i=@digital-infotech.net Yahoo: domainkeys=neutral (no sig);

Hello, Does anyone have a sample SELinux policy for dkim-milter? I'm using the configuration from this page: http://www.howtoforge.com/set-up-dkim-for-multiple-domains-on-postfix-with-dkim-milter-2.8.x-centos-5.3 Along with the latest RPM from the link on that page.

I created a client library to send emails for a webapp. After connecting to the SMTP server with credential setup in CPANEL, and then do NOT add Message-Id header, the DKIM signature 'h' record created by dovecot/WHM is wrong, and a Message-ID (with a capital D) header is added, invalidating the generated DKIM signature value. This causes outlook, yahoo, gmail and other email

Hello again, I noticed mails from the Dovecot list break DKIM signatures. Perhaps it's something to look at? Most lists I'm on manage to pass messages with DKIM intact. Authentication-Results: abc.abc.abc; dkim=fail (rsa verify failed) header.d=mrstuudio.ee header.s=mr header.b=M03Fp5lE; dmarc=pass (policy=none) header.from=dovecot.org; spf=pass Thanks, Reio -------------- next

A while back I struggled to get Domainkeys and DKIM to work properly on my little home server. While I'm sure they weren't necessary in a strict sense, it not only enabled me to learn about the technology but allowed for more of a verification of the email coming from my server. And so this week I figured: "Hey, this has been working without a problem for a while; it must be time to

Okay, Yahoo is bumming me. Only system my mail is having an issue with. All mail is accepted, but junked. I can only think it is the DKIM/Domain keys. It is apparent that the dkim-milter is not part of the centos 5.x distro nor is it part of the mirrors, as far as I can tell. So...have any of you done it with your servers for sendmail? There are some sites that claim to have rpms and I have
