Email::Sender::Transport::SMTP - send email over SMTP


version 1.300035


This transport is used to send email over SMTP, either with or without secure sockets (SSL/TLS). It is one of the most complex transports available, capable of partial success.

For a potentially more efficient version of this transport, see Email::Sender::Transport::SMTP::Persistent.


The following attributes may be passed to the constructor:

"hosts": an arrayref of names of the host to try, in order; defaults to a single element array containing "localhost"
The attribute "host" may be given, instead, which contains a single hostname.
"ssl": if 'starttls', use STARTTLS; if 'ssl' (or 1), connect securely; otherwise, no security
"ssl_options": passed to Net::SMTP constructor for 'ssl' connections or to starttls for 'starttls' connections; should contain extra options for IO::Socket::SSL
"port": port to connect to; defaults to 25 for non-SSL, 465 for 'ssl', 587 for 'starttls'
"timeout": maximum time in secs to wait for server; default is 120
"sasl_username": the username to use for auth; optional
"sasl_password": the password to use for auth; required if "sasl_username" is provided
"allow_partial_success": if true, will send data even if some recipients were rejected; defaults to false
"helo": what to say when saying HELO; no default
"localaddr": local address from which to connect
"localport": local port from which to connect
"debug": if true, put the Net::SMTP object in debug mode


If "allow_partial_success" was set when creating the transport, the transport may return Email::Sender::Success::Partial objects. Consult that module's documentation.
