  • Well, first, this is not an issue with the wordpress-software. Its an issue with the mailserver from

    I haven’t found another way to contact a suitable person, so i post it here 🙂
    In case I#m wrong here with this topic, so please tell me, who I can contact for.

    Dear, your mailserver ist not configured correctly. I dont receive any mails from So i tailed my maillog and grepped for “wordpress” and found the following messages….

    postfix/smtpd[14680]: warning: address not listed for hostname
    postfix/smtpd[14680]: NOQUEUE: reject: RCPT from unknown[]: 450 4.7.1 Client host rejected: cannot find your hostname, []; from=<> to=<me@my-mailserver.tld> proto=ESMTP helo=<>

    This is effecting mails from plugin-repository, this forum and I don’t know what else. And yes, this is a misconfiguration in your mailservers, not in mine. I also made a hostlookup by myself and found the following.

    host has address has address mail is handled by 10
    host has address has address
    host has address

    I hope this will be fixed as soon as possible, because I am not able to receive any mails from you, there all rejected.

    I’m not sure either, but I’ll poke around and see if I can find who can take a look.

    I’ll pass it along, but it sounds like your mailserver is being too picky in its rejection of emails. We send email from one of 10-odd different servers, not through a central mail server. Any of the various web servers can send email, it’s not limited in that manner.

    There is simply missing a reverse DNS, which is part of any propper configuration 🙂




    I am not sure why your mail server cannot find the PTR record for because it exists:

    ~ barry$ dig +short -x

    Can you troubleshoot that a bit more from your mail server and let us know what you find?

    It is true that the forward and reverse lookups don’t match – in order for that to happen we will have to change how things work a bit.


    With the dig-command I get the same result as you. But I added a whitelisting-system to my mailserver as a workaround, and I hope it works.

    I take a look what else my server can tell me 🙂
