Symptom/Problem: E-mails to MDaemon mailing lists are not archived into every users' archive, that are member of these mailing lists.

Root Cause: MDaemon does not write e-mail message headers that are requierd by MailStore to file in these e-mail correctly.

Solution: Disable the option Apply content & spam filters to list mail before cracking individual copies in MDaemon's Settings > Mailing List Manager > Mailing List Settings. Be aware that changing this setting may result in higher load on the MDaemon server, since multiple individual message will be scanned instead of one incoming message.
