Описание (Description)
The smtp utility is a Simple Mail Transfer Protocol (SMTP) client
which can be used to run an SMTP transaction against an SMTP
server.
By default, smtp reads the mail content from the standard input,
establishes an SMTP session, and runs an SMTP transaction for all
the specified recipients. The content is sent unaltered as mail
data.
The options are as follows:
-a authfile
Perform a login before sending the message. The username
and password are read from authfile and need to be on the
first and second line respectively. This option requires a
TLS or STARTTLS server.
-C Do not require server certificate to be valid.
-F from
Set the return-path (MAIL FROM) for the SMTP transaction.
Default to the current username.
-H helo
Define the hostname to advertise (HELO) when establishing
the SMTP session.
-h Display usage.
-n Do not actually execute a transaction, just try to
establish an SMTP session and quit. When this option is
given, no message is read from the standard input.
-s server
Specify the server to connect to and connection parameters.
The format is [proto://[user:pass@]]host[:port]. The
following protocols are available:
smtp Normal SMTP session with opportunistic
STARTTLS.
smtp+tls Normal SMTP session with mandatory STARTTLS.
smtp+notls Plain text SMTP session without TLS.
lmtp LMTP session with opportunistic STARTTLS.
lmtp+tls LMTP session with mandatory STARTTLS.
lmtp+notls Plain text LMTP session without TLS.
smtps SMTP session with forced TLS on connection.
Defaults to 'smtp://localhost:25'.
-v Be more verbose. This option can be specified multiple
times.
