Allow Duplicate Posting
A duplicate posting occurs when one person attempts to post a seemingly identical message to the same mailing list, more than once in one day. Please note: Archiving must be enabled
for Lyris List Manager to accurately detect a duplicate posting.
Lyris List Manager looks at the first 200 characters to determine if a posting appears to be a duplicate. The reason for this is that some "automatic answer" programs (such as the "vacation"
program) will automatically reply to anything they receive by adding a "I'm on vacation" sentence to the top of the message and quote the rest of the message. Lyris List Manager will catch the
duplicate posting, since the top of the message will be identical.
Normally, duplicate postings are the result of the author not being careful and sending the same message twice, or of some Internet mail error where the same message is delivered twice.
By default, Lyris List Manager rejects duplicate postings. Normally, you will want to leave this default setting as it is since, there usually is no good reason why your list members would want to
receive the same message twice. Also, this feature is quite effective as a mail-loop prevention technique, when people attach a misbehaving "automatic email answering" program to their email
address. Most "vacation" programs are well behaved and do not answer list-mail (they detect the "Precedence: bulk" message header). However, people sometimes decide to write their own "vacation"
program or other automatic email generating program and this can cause problems on a list. This feature takes care of this problem.
