similar to: DKIM fail if WHM adds Message-ID, should be Message-Id

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

>>"Never use a browser for email." I don't agree. In fact, using a browser for email or atleast initial setup, is actually more secure. This because SMTP/IMAP clients normally don't support 2FA, so you would have to "hack" a solution to enable 2FA for email. This can be made in 2 ways: Either, you have a full fledged email setup. Whats important, is, to prevent

I am investigating whether dovecot(https://github.com/dovecot/core/) handles case insensitive Message-ID headers as per RFC. I can't raise a support issue with cPanel team (https://tickets.cpanel.net/review/login.cgi) as that needs an paid account with them. There may be an issue with the CPANEL/WHM DKIM module. Is the source code online? Rob

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

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 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. I have sendmail-devel installed Here is the tail of the result output of sh ./Build make[2]: cc: Command not found make[2]: *** [assert.o] Error 127 make[2]: Leaving directory

message sent from the sieve-vacation does not contain dkim signature how to configure sieve to send messages via smtp transport with signing?

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

Dear Friends, is anyone is able to setup DKIM with FreeBSD 9.0 and Postfix? thanks / Prabhpal

Hi guys, when I send e-mails to CentOS mailing list <centos at centos.org>, I received DMARC / DKIM failure reports. Is it possible to solve this problem and if so how? This is the first report: This is an email abuse report for an email message received from IP 208.100.23.70 on Tue, 17 Sep 2019 15:56:25 +0200. The message below did not meet the sending domain's DMARC policy. For

Hello, I'm trying to implement domainkeys and dkim on my domain and then to get it set up with postfix. Currently i'm having difficulty with the first stage, adding the domainkey txt record to bind, is a special version of bind required to do this? The machine that handles dns is using bind 9.5.1-p3. Thanks. Dave.

Hi Tobias, Here is something I acquired from this mailing list some years ago. It works well for me: #---run in previous version (e.g. R 3.1.0) packages <- installed.packages()[,"Package"] save(packages, file="Rpackages_R3.1.0") #---run in new version load("Rpackages_R3.1.0") for (p in setdiff(packages, installed.packages()[,"Package"]))

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
