man Mail::Transport () - base class for message exchange

NAME

Mail::Transport - base class for message exchange

INHERITANCE

 Mail::Transport
   is a Mail::Reporter


 Mail::Transport is extended by
   Mail::Transport::Receive
   Mail::Transport::Send

SYNOPSIS

 my $message = Mail::Message->new(...);


 # Some extensions implement sending:
 $message->send;
 $message->send(via => 'sendmail');


 my $sender = Mail::Transport::SMTP->new(...);
 $sender->send($message);


 # Some extensions implement receiving:
 my $receiver = Mail::Transport::POP3->new(...);
 $message = $receiver->receive;

DESCRIPTION

Objects which extend CWMail::Transport implement sending and/or receiving of messages, using various protocols.

Mail::Transport::Send extends this class, and offers general functionality for send protocols, like SMTP. Mail::Transport::Receive also extends this class, and offers receive method. Some transport protocols will implement both sending and receiving.

METHODS

Constructors

Mail::Transport->new(OPTIONS) 

 Option      Defined in       Default       
 executable                   C<undef>      
 hostname                     C<'localhost'>
 interval                     C<30>         
 log         L<Mail::Reporter>  C<'WARNINGS'> 
 password                     undef         
 port                         undef         
 proxy                        undef         
 retry                        <false>       
 timeout                      C<120>        
 trace       L<Mail::Reporter>  C<'WARNINGS'> 
 username                     undef         
 via                          C<'sendmail'>
. executable FILENAME If you specify an executable, the module does not need to search the system directories to figure-out where the client lives. Using this decreases the flexible usage of your program: moving your program to other systems may involve changing the path to the executable, which otherwise would work auto-detect and unmodified. . hostname HOSTNAME|ARRAY-OF-HOSTNAMES The host on which the server runs. Some protocols accept an array of alternatives for this option. . interval SECONDS The time between tries to contact the remote server for sending or receiving a message in SECONDS. This number must be larger than 0. . log LEVEL . password STRING Some protocols require a password to be given, usually in combination with a password. . port INTEGER The port number behind which the service is hiding on the remote server. . proxy PATH The name of the proxy software (the protocol handler). This must be the name (preferable the absolute path) of your mail delivery software. . retry NUMBER|undef The number of retries before the sending will fail. If CWundef, the number of retries is unlimited. . timeout SECONDS SECONDS till time-out while establishing the connection to a remote server. . trace LEVEL . username STRING Some protocols require a user to login. . via CLASS|NAME Which CLASS (extending CWMail::Transport) will transport the data. Some predefined NAMEs avoid long class names: CWmail and CWmailx are handled by the Mail::Transport::Mailx module, CWsendmail and CWpostfix belong to Mail::Transport::Sendmail, and CWsmtp is implemented in Mail::Transport::SMTP. The CWpop or CWpop3 protocol implementation can be found in Mail::Transport::POP3.

Server connection

$obj->findBinary(NAME [, DIRECTORIES]) Look for a binary with the specified NAME in the directories which are defined to be safe. The list of standard directories is followed by the optional DIRECTORIES. The full pathname is returned. You may specify new(proxy), which specifies the absolute name of the binary to be used.

$obj->remoteHost Returns the hostname, port number, username and password to be used to establish the connection to the server for sending or receiving mail.

$obj->retry Returns the retry interval, retry count, and timeout for the connection.

DIAGNOSTICS

Warning: Avoid program abuse: specify an absolute path for CW$exec.

Specifying explicit locations for executables of email transfer agents should only be done with absolute file names, to avoid various pontential security problems.

Warning: Executable CW$exec does not exist.

The explicitly indicated mail transfer agent does not exists. The normal settings are used to find the correct location.

Error: Package CW$package does not implement CW$method.

Fatal error: the specific package (or one of its superclasses) does not implement this method where it should. This message means that some other related classes do implement this method however the class at hand does not. Probably you should investigate this and probably inform the author of the package.
