The following info applies to advanced email settings:
These port settings should be provided by your email provider or corporate admin:
Secure SMTP (SSMTP): 465
Secure IMAP (IMAP4-SSL): 585
IMAP4 over SSL (IMAPS): 993
Secure POP3 (SSL-POP): 99
To use a non-standard port, add a colon (:) followed by the port number to the end of the server name.
For example, if your incoming mail server (pop.mailserver.net) communicates via port 115, the server would be configured as pop.mailserver.net:115.
may require Authenticated SMTP (ASMTP).
ASMTP uses some form of authentication (username/password, IP address, etc.) to verify that a sender is authorized to send messages using that particular server.
If the provider uses an IP address or IP range for authentication, you must establish a dial-up connection to the ISP/SMTP provider. This ensures you are assigned a valid IP address for authentication. Otherwise, attempts to send fail.
If the provider uses a username/password combination to authenticate senders:
The combination must be valid for both the incoming and outgoing servers.
Some email clients do not support ASMTP that is independent of the incoming username/password. In these cases, you may not be able to retrieve email from one provider and send using another.
