I have my own VPS where a site is running (control panel: directadmin). When I send mails, some are being delivered (hotmail, gmail, me@somedomain.com ,...), others are not (me@somedomain2.com), others are delivered after being greylisted (me@somedomain3.com).

/var/log/exim/mainlog

What could be the cause of this? Is the problem Sender-Side or Receiver-Side? case 1: me@somedomain.com (delivered)

Notice that the "from" in case1 differs in case2: fiveyears@mydomain.com or info@mydomain.com.
