Ini karena versi MDaemon yang Anda gunakan tidak menggunakan NULL
reverse path saat kirim autoresponder message

http://www.mail-archive.com/[email protected]/msg15010.html

o [7154] The option to use a NULL reverse path when sending system
  generated messages has been removed from Preferences.  MDaemon will
now ALWAYS use a NULL reverse path when required (for example, with
DSN's)  and will NOT use a NULL reverse path when not required (such as
with auto-responders and HELP responses, etc).  Rather than NULL,
MDaemon will use "noreply@" in order to detect and prevent mail loops.
In previous versions MDaemon used "MDaemon@".  These changes are
necessary in order   to better comply with a SHOULD found in section
4.5.5 of RFC 2821 which after describing DSNs reads thus:

  "All other types of messages (i.e., any message which is not required
   by a standards-track RFC to have a null reverse-path) SHOULD be sent
   with with a valid, non-null reverse-path."

Mestinya sih loop detector akan menghentikan mail loop ini

Maximum message hop count before message placed in bad queue: 25
