IMAP Email Server Capabilities Scanner Detail

You can scan IMAP email servers by using this tool.

Retrieves IMAP email server capabilities.

IMAP4rev1 capabilities are defined in RFC 3501. The CAPABILITY command allows a client to ask a server what commands it supports and possibly any site-specific policy.

Some Advice for Common Problems

For client requests, the default port for IMAP is port 143, but for IMAP over TLS, port 993 is specified; setting all clients and servers to use port 993 can help avoid plaintext connections. Connections on the unsecured port 143 can potentially be blocked by firewalls and other gateway systems.
