    Hi

    this means that you reaches the greylist of the Gmail's mail server, so you are considered as a spam for gmail.

    The website "web1" on your server seems to send out spam. You can see the website ID in the sender address.

    take a look at the conatnt of the spam email with:

    postcat /var/spool/postfix/deferred/6/68A5E20216E

    the mail header that oyu see there should contain the name of the spam sending php script, when the site is written in php.
     
  4. SPAM or tests ???

    Hi,

    Can this be due to some tests we made? 5-10 mails, some the same and some slightly different??

    web1 is my own shop and I'm a little lost here. I setup "normal" email security at the mail accounts used for this site.

    I received some spam during the last 3 months. 3-4 every month. Just transferred it to JUNK and thought that was that.

    The problem is, that some of our mail accounts for the shop appears on the site. I know it's not very smart, but some times we need to do it this way.

    Can one of these issues be the source of the problem?
