    Hi All,

    I just spent the last two hours looking into this. Messages sent to my mailman lists were not being sent out, but all other features/messages affiliated with mailman worked. E.g. if I subscribed a new user, that user would get a confirmation and the owner would as well.

    I found the issue. When Mailman rebroadcasts the mail, it does not preserve the DKIM or reply-to email addresses resulting in a DKIM failure. Since I had my EXIM set to reject DKIM failures, it wouldn't rebroadcast these messages out to the list. /usr/local/cpanel/3rdparty/mailman/logs/smtp-failure shows:

    Aug 21 23:08:20 2013 (2812) SMTP session failure: 550, DKIM: encountered the following problem validating glexia.com:
    signature_incorrect, msgid: <CAGj=18Eho6MwiO3m03t8Jzc38U7+Q1aY_8284WbwdPgCdxaQVQ@mail.gmail.com>
    Aug 21 23:10:07 2013 (2812) SMTP session failure: 550, DKIM: encountered the following problem validating glexia.com:
    signature_incorrect, msgid: <CAGj=18E4ZapqUnrvaCHFDRzGtWsyrUe9PYBhmr3Xzjw3wxNnRg@mail.gmail.com>

    I don't know why the DKIM was failing because I have a valid DKIM signature. Furthermore, I've tested the DKIM validity on my outgoing mail and it worked fine.

    To solve the issue I had to turn off DKIM rejection on my EXIM server. Could you please fix this issue?

    Regards,

    Glexia

    To update, we were not able to reproduce this issue due to a lack of authentication details. If anyone else experiences the same problem, feel free to open a support ticket so we can take a closer look.

    Thank you.
