MSGSEP defines the Perl regular expression that represents the message separator for mailbox files.
Note: There is a space character after
Some MTAs do not escape lines that start with "From ". This will cause MHonArc to split a message into separate messages since it will treat the line as a message separator (if MHonArc is processing a mailbox file). One way to help avoid this problem is to set the MSGSEP resource to a more specific regular expression. For example:
<MSGSEP> ^From \S+\s+\S+\s+\S+\s+\d+\s+\d+:\d+:\d+\s+\d+ </MSGSEP>
It is still possible to get bogus splitting if a message contains a line that matches the regexp. Therefore, you may want to activate the CONLEN resource, if applicable.
