Only unencrypted passwords get hidden. These include passwords used with regular POP3 or POP-before-SMTP authentications, SASL LOGIN, and SASL PLAIN authentication methods. Secure authentication methods (such as APOP or SASL NTLM) do not transmit passwords over the network, so the password data never appear in the log anyway.
The pattern to replace passwords is taken from PrivateDataCover value.
|Setting this property to false may expose security problems. Anybody who has access to the log file might be able to see the actual password data which was trasmitted by the component to the mail server.|
