Specify the email protocol, such as smtp, used by the email server configured for your site.
N4 supports Simple Mail Transfer Protocol (SMTP) over Secure Sockets Layer (SSL). See MSEMAIL_SERVER_CONFIG005 (SMTPS USER) (on page 1) and MSEMAIL_SERVER_CONFIG006 (SMTPS_PASSWORD) (on page 1).
N4 email notification works with either smtp or smtps protocol. Enter the protocol in lower case smtp or smtps. (It will not work in upper case.)
The email client can use either protocol POP3 with port 110 or IMAP with port 143 for email retrieval. The protocol IMAP is only for retrieving emails.
Make sure the setting is updated correctly at the Global scope level.. When you use the option Forgot Password, N4 uses the system default user at the Global level to generate the email for the password.
