    Hi,

    I have a huge problem at the moment. My Debian 4.0 server has postfix/2.3.8 installed and properly running. Now, whenever I try to send mail using for instance a "lost password" form on a website that is hosted on that server the mail is not reaching the recipient but seems to stay in the queue.

    If I run 'mailq' I see all those messages that are send out saying:

    (host mx0.mysega.de[80.237.138.5] said: 451 Temporary local problem - please try later (in reply to RCPT TO command))

    Now, placesto.be is the hostname of the server and mysega is the address of the recipient.

    Below are main.cf and master.cf, if you need any more information let me know please. Thanks for trying to help me in advance ;)

    Does this happen only with this recipient, or with all recipients (also recipients on other servers)? Because this looks like a problem on the receiving mail server to me, not a problem with your mail server.

    Are there any errors in your mail log? Have you checked if your server is blacklisted? http://www.mxtoolbox.com/blacklists.aspx
