Old POP3 behavior
(since 5.3.447.3)
There’s a registry option to allow the POP3 server to behavior the "old way" in regards to "marking/deleting" received email via POP3. To enable the old behavior,
create a registry option called EnableSecurityHole at the registry location:
|
HKEY_CURRENT_USER\Software\MSI\Wildcat\WcPOP3
Type: DWORD
EnableSecurityHole=1 (0 to disable)
|
NOTE: THIS OPTION IS NOT RECOMMENDED BY SANTRONICS FOR NORMAL OPERATIONS.
The reason why it was called "EnableSecurityHole" is because that is exactly what it is - a
security hole to your mail system. If this option is enabled, your POP3 clients will be able to
"SNOOP" at his mail without allowing anyone, including the Wildcat! Server, to ever know the mail
was received. Acknowledgments, receipt requests will not work any more, and your mail server will be overloaded with redundant server mail operations penalizing the performance of your
system. Again, people who write mail for POP3 clients will never know the POP3 client has received the mail. No other mail reading entry point into WINSERVER allows this. POP3 is the only
method users can do this if you enable this option. Hence, this option is NOT recommended by
Santronics. If sysops send us "Mail Server Slow Performance" reports with their pop3 clients, you now know what we will ask you do remove.
The recommended approach is to only enable mail snooping to certain "roaming" users. Roamers
are POP3 clients who query a mail server from multiple machines. If you wish to offer mail snooping to roamers, then define a user define variable called POP3Snoop
for the user's record. Set POP3SNOOP=1 and the user will be able to read his mail without marking it as received.
However, if the user request to delete the mail, it will be honored.
