Can any one gave me requirements/step-by-step procedures on how am I suppose to create DomainKeys for my mail server so that our email can pass through on Yahoo!'s mail server without being marked as spam or bulk mail? I think implementing DomainKeys is one of the requirements of Yahoo! Mail to not have email marked as spam. Our mail s...
I'm hacking some support for DomainKeys and DKIM into an open source email marketing program, which uses a python script to send the actual emails via SMTP. I decided to go the quick and dirty route, and just write a perl script that accepts an email message from STDIN, signs it, then returns it signed. What I would like to do, is from ...
Hello, I have setup PostFix for receiving emails only. I want to authenticate the received emails against their sender email addresses by using SPF or DKIM. Is there a good java plugin available for this? or do i need to write my own in java (other preferences C, C ++) ,please reply with relevant references. Thanks in advance Ashish...

I'll admit I'm not very adept at key verification. What I have is a script that downloads messages from a POP3 server, and I'm attempting to verify the DKIM signatures in PHP. I've already figured out the body hash (bh) validation check, but I can't figure out the header validation. http://www.dkim.org/specs/rfc4871-dkimbase.html#rfc.se...
I'm writing a C# DKIM validator and have come across a problem that I cannot solve. Right now I am working on calculating the body hash, as described in Section 3.7 Computing the Message Hashes. I am working with emails that I have dumped using a modified version of EdgeTransportAsyncLogging sample in the Exchange 2010 Transport Agent SD...
It looks like there are some great libraries out there to do DomainKeys signing of emails on C#/.NET, but I'm having a really hard time finding the same kind of support for PHP. Maybe I'm not looking in the right place? The only one I found is http://php-dkim.sourceforge.net/; it looks incredibly hacky and supports PHP4 only. Consideri...
Hi, I have setup a postfix mail receiving server. On this I am using DKIM milter to verify incoming mail DKIM signatures. From some email clients I am getting the following 'bad signature data' error: Jun 7 02:10:09 ip-10-194-99-63 dkim-filter[27964]: (unknown-jobid) no signing domain match for `gmail.com' Jun 7 02:10:09 ip-10-19...
I need to add DKIM to a Postfix installation. I've found two implementations that work with Postfix. OpenDKIM (http://www.opendkim.org/), and dkim-milter (http://sourceforge.net/projects/dkim-milter/). The former claims to be a fork of the latter. OpenDKIM appears to be the more active project, judging from releases and mailing list ...
I have a script that is sending emails via SMTP and I'm trying to get it to sign emails with a DKIM signature using CPAN's Mail::DKIM::Signer. The trouble is I am getting error that the body hash is invalid. For example I sent the email below to the port25.com verifier and it is telling me the body hash it expected is "QFBPfFyqSONobf7fNo...
Hello everybody. I send automated mails to hotmail users. (thank you for your registration bla bla) Because plain text doesn't look attractive enough, I use HTML with images. The images reside on a public webserver. As SMTP server I use the SMTP part of IIS 7.5 (windows 2008 R2). I have an SPF record setup in the DNS. I have also read ...
