Retrieving POP3 headers
You can specify how the probe handles POP3 headers using the Forgetpop3TopHeader property.
Some server software, including some versions of Microsoft Exchange and IBM® Lotus Notes, returns slightly different
headers each time the POP3 TOP and RETR commands
are used. To ensure that message content returned by the RETR command
is properly parsed, it is better in these cases to also use the headers
returned by the RETR command.
Use the Forgetpop3TopHeader property
to specify whether or not the probe forgets headers that have been
retrieved by the TOP command and uses those retrieved
by the RETR command instead.
