Standard Email Messaging Ports
The following info applies to advanced email settings:
-
These port settings should be provided by your email provider or corporate admin:
- POP3: 110
- IMAP: 143
- SMTP: 25
- 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.
-
ISP/SMTP providers:
-
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.
- To obtain individual server settings, refer to Common Email Server Addresses.
