Creates a new Net::SMTP object and connects to the server.
This method is equivalent to:
Net::SMTP.new(address, port).start(helo_domain, account, password, authtype)
Net::SMTP.start('your.smtp.server') do |smtp| smtp.send_message msgstr, 'from@example.com', ['dest@example.com'] end
If called with a block, the newly-opened Net::SMTP object is yielded to the block, and automatically closed when the block finishes. If called without a block, the newly-opened Net::SMTP object is returned to the caller, and it is the caller’s responsibility to close it when finished.
address is the hostname or ip address of your smtp server.
port is the port to connect to; it defaults to port 25.
helo is the HELO domain provided by the client to the server (see overview comments); it defaults to ‘localhost’.
The remaining arguments are used for SMTP authentication, if required or desired. user is the account name; secret is your password or other authentication token; and authtype is the authentication type, one of :plain, :login, or :cram_md5. See the discussion of SMTP Authentication in the overview notes.
This method may raise:
true if the SMTP session has been started.
Opens a TCP connection and starts the SMTP session.
helo is the HELO domain that you’ll dispatch mails from; see the discussion in the overview notes.
If both of user and secret are given, SMTP authentication will be attempted using the AUTH command. authtype specifies the type of authentication to attempt; it must be one of :login, :plain, and :cram_md5. See the notes on SMTP Authentication in the overview.
When this methods is called with a block, the newly-started SMTP object is yielded to the block, and automatically closed after the block call finishes. Otherwise, it is the caller’s responsibility to close the session when finished.
This is very similar to the class method SMTP.start.
require 'net/smtp' smtp = Net::SMTP.new('smtp.mail.server', 25) smtp.start(helo_domain, account, password, authtype) do |smtp| smtp.send_message msgstr, 'from@example.com', ['dest@example.com'] end
The primary use of this method (as opposed to SMTP.start) is probably to set debugging (set_debug_output) or ESMTP (esmtp=), which must be done before the session is started.
If session has already been started, an IOError will be raised.
This method may raise:
Inserts switch at the head of the list, and associates short, long and negated long options. Arguments are:
switch
OptionParser::Switch instance to be inserted.
short_opts
List of short style options.
long_opts
List of long style options.
nolong_opts
List of long style options with “no-” prefix.
prepend(switch, short_opts, long_opts, nolong_opts)
Pushes back erred argument(s) to argv.
Returns error reason. Override this for I18N.
Appends sep to the text to be output. By default sep is ‘ ’
width argument is here for compatibility. It is a noop argument.
This is used as a predicate, and ought to be called first.
Rewinds the internal position for enumeration.
See Enumerator#rewind.
Gets the IP address of name from the hosts file.
Gets all IP addresses for name from the hosts file.
Gets the IP address of name from the DNS resolver.
name can be a Resolv::DNS::Name or a String. Retrieved address will be a Resolv::IPv4 or Resolv::IPv6
Gets all IP addresses for name from the DNS resolver.
name can be a Resolv::DNS::Name or a String. Retrieved addresses will be a Resolv::IPv4 or Resolv::IPv6
Look up the typeclass DNS resource of name.
name must be a Resolv::DNS::Name or a String.
typeclass should be one of the following:
Resolv::DNS::Resource::IN::ANY
Resolv::DNS::Resource::IN::CNAME
Resolv::DNS::Resource::IN::HINFO
Resolv::DNS::Resource::IN::MINFO
Resolv::DNS::Resource::IN::MX
Resolv::DNS::Resource::IN::NS
Resolv::DNS::Resource::IN::PTR
Resolv::DNS::Resource::IN::SOA
Resolv::DNS::Resource::IN::TXT
Returned resource is represented as a Resolv::DNS::Resource instance, i.e. Resolv::DNS::Resource::IN::A.
Looks up all typeclass DNS resources for name. See getresource for argument details.
