    Any help for this:

    Today all of our clients (almost) called and told us that they can't send mails out.

    The get following message:

    Host xxx.xxx.xxx.xxx is not permitted to relay through server.xxxxxx.xxx.
    Perhahps you have not logged into the pop/imap server the last 30 minutes.
    You may also have been rejected because your ip addr.


    We did not change anything - we only made the recommended security update.

    Any help would be great!
    Thanks!!

    I'm guessing this is when they try to use your server as SMTP server for outgoing mail. Tell your clients to set their email clients to use &POP Before SMTP& authentication. It's a security feature to stop people that do not have an email account from using your server to send out email (mainly SPAM).
