This parameter controls the security around
authentication. The security settings are configured with the logintype parameter, which has the
following options:
??‘ PlainTextLogin requires no encryption (TLS or SSL) over the standard POP3 (110) and IMAP4
(143) ports. Usernames and passwords are in clear text, so this is not practical in a production
network. It may be useful for troubleshooting purposes.
??‘ PlainTextAuthentication still requires no encryption over the standard ports, but Basic
Authentication is permitted only on the secure ports POP3 (995) and IMAP4 (993). Clients can
be configured to use Secure Password Authentication (SPA), which is Windows Integrated
Authentication, and not use SSL.
??‘ SecureLogin is the default logintype. This configuration requires TLS or SSL encryption before
authenticating.
This example sets the IMAP4 logintype to plaintext:
Set-ImapSettings -logintype plaintextlogin
Restarting the POP3 and IMAP4 services is required before configuration changes take effect.
A handy trick to finding out valid parameter values is to pass a made - up value. The error sometimes will
contain a list of valid choices, as shown in Figure 6 - 4 .
If the organization will heavily use IMAP4, there are some additional parameters to configure.
The MaxConnections parameter sets the maximum number of connections for IMAP4.
