User checklist for "non delivered messages"

  1. Checked Junk/Spam folder in the receiving mailbox.
  2. Check sender mailbox for bounce (delivery problem report) mail messages.
    You may receive first "warning email" after a few hours (e.g. 4h) of failing delivery attempts.
  3. Some botched anti-spam system throw away messages "classified as spam" without any hint to the sender or the recipient -> ask admin/postmaster of the receiving mail server

This can also quite often be because of the mail relay server you are using (where the SMTP mail is routing through from the Linux box) not having been set up properly with public RDNS records. Many mail servers reject mail that comes from a domain without the appropriate RDNS configuration.
