21 This module implements transport of "Mail::Message" objects by
22 negotiating to the destination host directly by using the SMTP
23 protocol, without help of "sendmail", "mail", or other programs on the
24 local host.
25 warning: you may need to install Net::SMTPS, to get TLS support.

54 esmtp_options => HASH
56 [2.116] ESMTP options to pass to Net::SMTP. See the Net::SMTP
57 documentation for full details. Options can also be passed at
58 send time. For example: "{ XVERP => 1 }"
59 executable => FILENAME
61 from => ADDRESS
62 Allows a default sender address to be specified globally. See
63 trySend() for full details.
64 helo => HOST
66 The fully qualified name of the sender's host (your system) which
67 is used for the greeting message to the receiver. If not
68 specified, Net::Config or else Net::Domain are questioned to find
69 it. When even these do not supply a valid name, the name of the
70 domain in the "From" line of the message is assumed.
71 hostname => HOSTNAME|ARRAY
73 interval => SECONDS
74 log => LEVEL
75 password => STRING
76 The password to be used with the new(username) to log in to the
77 remote server.
78 port => INTEGER
80 proxy => PATH
81 retry => NUMBER|undef
82 smtp_debug => BOOLEAN
83 Simulate transmission: the SMTP protocol output will be sent to
84 your screen.
85 timeout => SECONDS
87 The number of seconds to wait for a valid response from the
88 server before failing.
89 trace => LEVEL
91 username => STRING
92 Use SASL authentication to contact the remote SMTP server
93 (RFC2554). This username in combination with new(password) is
94 passed as arguments to Net::SMTP method auth. Other forms of
95 authentication are not supported by Net::SMTP. The "username"
96 can also be specified as an Authen::SASL object.
97 via => CLASS|NAME
99 Sending mail
101 Extends "Sending mail" in Mail::Transport::Send.
102 $obj->destinations( $message, [$address|ARRAY] )
104 Inherited, see "Sending mail" in Mail::Transport::Send
105 $obj->putContent($message, $fh, %options)
107 Inherited, see "Sending mail" in Mail::Transport::Send
108 $obj->send($message, %options)
110 Inherited, see "Sending mail" in Mail::Transport::Send
111 $obj->trySend($message, %options)
113 Try to send the $message once. This may fail, in which case this
114 method will return "false". In list context, the reason for
115 failure can be caught: in list context "trySend" will return a list
116 of six values:
117 (success, rc, rc-text, error location, quit success, accept)
119 Success and quit success are booleans. The error code and -text
121 are protocol specific codes and texts. The location tells where
122 the problem occurred.
123 [3.003] the 'accept' returns the message of the dataend()
125 instruction. Some servers may provide useful information in there,
126 like an internal message registration id. For example, postfix may
127 return "2.0.0 Ok: queued as 303EA380EE". You can only use this
128 parameter when running local delivery (which is a smart choice
129 anyway)
130 -Option --Default
132 esmtp_options {}
133 from < >
134 to []
135 esmtp_options => HASH
137 Additional or overridden EMSTP options. See new(esmtp_options)
138 from => ADDRESS
140 Your own identification. This may be fake. If not specified, it
141 is taken from Mail::Message::sender(), which means the content of
142 the "Sender" field of the message or the first address of the
143 "From" field. This defaults to "< >", which represents "no
144 address".
145 to => ADDRESS|[ADDRESSES]
147 Alternative destinations. If not specified, the "To", "Cc" and
148 "Bcc" fields of the header are used. An address is a string or a
149 Mail::Address object.
150 Server connection
152 Extends "Server connection" in Mail::Transport::Send.
153 $obj->contactAnyServer()
155 Creates the connection to the SMTP server. When more than one
156 hostname was specified, the first which accepts a connection is
157 taken. An IO::Socket::INET object is returned.
158 $obj->findBinary( $name, [@directories] )
160 Inherited, see "Server connection" in Mail::Transport
161 $obj->remoteHost()
163 Inherited, see "Server connection" in Mail::Transport
164 $obj->retry()
166 Inherited, see "Server connection" in Mail::Transport
167 $obj->tryConnectTo($host, %options)
169 Try to establish a connection to deliver SMTP to the specified
170 $host. The %options are passed to the "new" method of Net::SMTP.
171 Error handling
173 Extends "Error handling" in Mail::Transport::Send.
174 $obj->AUTOLOAD()
176 Inherited, see "Error handling" in Mail::Reporter

223 Warning: Message has no destination
224 It was not possible to figure-out where the message is intended to
225 go to.
226 Notice: No addresses found to send the message to, no connection made
228 Error: Package $package does not implement $method.
229 Fatal error: the specific package (or one of its superclasses) does
230 not implement this method where it should. This message means that
231 some other related classes do implement this method however the
232 class at hand does not. Probably you should investigate this and
233 probably inform the author of the package.
234 Warning: Resent group does not specify a destination
236 The message which is sent is the result of a bounce (for instance
237 created with Mail::Message::bounce()), and therefore starts with a
238 "Received" header field. With the "bounce", the new destination(s)
239 of the message are given, which should be included as "Resent-To",
240 "Resent-Cc", and "Resent-Bcc".
241 The "To", "Cc", and "Bcc" header information is only used if no
243 "Received" was found. That seems to be the best explanation of the
244 RFC.
245 As alternative, you may also specify the "to" option to some of the
247 senders (for instance Mail::Transport::SMTP::send(to) to overrule
248 any information found in the message itself about the destination.
