PHP IMAP extension makes use of c-Client library for IMAP protocol-specific functions. These days, many email clients, Gmail and Yahoo included, use both port 465 (for Implicit SSL/TLS) and 587 (for Explicit SSL/TLS), while others limit themselves only to 587. In doubt, use TLS/SSL, since it's more secure :) They usually use different ports, but it's common for mail servers to support both on both ports (so they support a broader range of clients).Ĭipher and TLS version choice is based on client-server negotiation, but STARTTLS could be understood as a less-capable client or server, then the parameters for decision differ.ĪFAIK, there's no limitation on the usage of TLS1.1 and TLS1.2 when connecting through STARTTLS, but they do connect differently than TLS/SSL. Basically StatTLS connects to an unencrypted port/connection and then asks for encryption, while TLS/SSL sessions are encrypted before any text is transmitted (see STARTTLS).
