XMail automatically detects and stops looping messages.
They get frozen in the message queue so they can be examined
for the reason of looping.

Loops can be caused by
- A too low "MaxMTAOps" value in your server.tab. Details see manual. 
- entries in aliases.tab or MailRoot/cmdaliases pointing to each other,
- entries in mailusers.tab with the same account ID,
- filters that redirect mails in a loop,
- DNS misconfiguration,
- a not commented-out "DefaultSMTPGateways" entry in your server.tab,
  which points to some nonsense targets.

For LINUX (and its flavours), only:
If you get looping messages  on a fresh or changed installation,
then this can be the cause:
- You have assigned the same hostname to multiple interfaces. Check
  your /etc/hosts.
- The permissions for /var/MailRoot/* is not 700. Make sure you did a
  'chmod -R 700 /var/MailRoot' after installation.
- The owner of /var/MailRoot needs to be root:root, nothing else. Check
  this with 'ls -la'. To transfer ownership to root do a
  'chown -R root:root /var/MailRoot'.
