new

Creates a new Net::IMAP object and connects it to the specified host.

options is an option hash, each key of which is a symbol.

The available options are:

port

port number (default value is 143 for imap, or 993 for imaps)

ssl

if options is true, then an attempt will be made to use SSL (now TLS) to connect to the server. For this to work OpenSSL [OSSL] and the Ruby OpenSSL [RSSL] extensions need to be installed. if options is a hash, it's passed to OpenSSL::SSL::SSLContext#set_params as parameters.

The most common errors are:

Errno::ECONNREFUSED

connection refused by host or an intervening firewall.

Errno::ETIMEDOUT

connection timed out (possibly due to packets being dropped by an intervening firewall).

Errno::ENETUNREACH

there is no route to that network.

SocketError

hostname not known or other socket error.

Net::IMAP::ByeResponseError

we connected to the host, but they immediately said goodbye to us.
