use Mail::Sendmail; %mail = ( To => 'you@there.com', From => 'me@here.com', Message => "This is a very short message" ); sendmail(%mail) or die $Mail::Sendmail::error; print "OK. Log says:\n", $Mail::Sendmail::log;
Mail::Sendmail takes a hash with the message to send and sends it to your mail server. It is intended to be very easy to setup and use. See also ``FEATURES'' below, and as usual, read this documentation.
There is also a FAQ (see ``NOTES'').
perl Makefile.PL
make
make test
make install
(eg. c:\Perl\site\lib\Mail\
or /usr/lib/perl5/site_perl/Mail/
or whatever it is on your system.
They are listed when you type C< perl -V >)
ppm install --location=http://alma.ch/perl/ppm Mail-Sendmail
or
ppm install http://alma.ch/perl/ppm/Mail-Sendmail.ppd
But this way you don't get a chance to have a look at other files (Changes, Todo, test.pl, ...).
At the top of Sendmail.pm, set your default SMTP server(s), unless you specify it with each message, or want to use the default (localhost).
Install MIME::QuotedPrint. This is not required but strongly recommended.
Bcc: and Cc: support.
Allows real names in From:, To: and Cc: fields
Doesn't send an X-Mailer: header (unless you do), and allows you to send any header(s) you want.
Configurable retries and use of alternate servers if your mail server is down
Good plain text error reporting
Experimental support for SMTP AUTHentication
Since the whole message is in memory, it's not suitable for sending very big attached files.
The SMTP server has to be set manually in Sendmail.pm or in your script, unless you have a mail server on localhost.
Doesn't work on OpenVMS, I was told. Cannot test this myself.
"unshift @{$Mail::Sendmail::mailcfg{'smtp'}} , 'my.mail.server';"
Alternatively, you can specify the server in the %mail hash you send from your script, which will do the same thing:
"$mail{smtp} = 'my.mail.server';"
A future version will (hopefully) try to set useful defaults for you during the Makefile.PL.
"sendmail(%mail) || print "Error sending mail: $Mail::Sendmail::error\n";"
It takes a hash containing the full message, with keys for all headers and the body, as well as for some specific options.
It returns 1 on success or 0 on error, and rewrites $Mail::Sendmail::error and $Mail::Sendmail::log.
Keys are NOT case-sensitive.
The colon after headers is not necessary.
The Body part key can be called 'Body', 'Message' or 'Text'.
The SMTP server key can be called 'Smtp' or 'Server'. If the connection to this one fails, the other ones in $mailcfg{smtp} will still be tried.
The following headers are added unless you specify them yourself:
Mime-Version: 1.0
Content-Type: 'text/plain; charset="iso-8859-1"'
Content-Transfer-Encoding: quoted-printable
or (if MIME::QuotedPrint not installed)
Content-Transfer-Encoding: 8bit
Date: [string returned by time_to_date()]
If you wish to use an envelope sender address different than the From: address, set $mail{Sender} in your %mail hash.
The following are not exported by default, but you can still access them with their full name, or request their export on the use line like in: "use Mail::Sendmail qw(sendmail $address_rx time_to_date);"
embedding options in your %mail hash
The following options can be set in your %mail hash. The corresponding keys will be removed before sending the mail.
$mail{server}='my.smtp.server:2525' will try to connect to port 2525 on server my.smtp.server
$mail{auth} = \%options; or $mail{auth} = {user=>``username'', password=>``password'', method=>``DIGEST-MD5'', required=>0 };
(different auth for different servers?)
A correct regex for valid e-mail addresses was written by one of the judges in the obfuscated Perl contest... :-) It is quite big. This one is an attempt to a reasonable compromise, and should accept all real-world internet style addresses. The domain part is required and comments or characters that would need to be quoted are not supported.
Example:
$rx = $Mail::Sendmail::address_rx;
if (/$rx/) {
$address=$1;
$user=$2;
$domain=$3;
}
The keys are not case-sensitive: they are all converted to lowercase before use. Writing "$mailcfg{Port} = 2525;" is OK: the default $mailcfg{port} (25) will be deleted and replaced with your new value of 2525.
This is a reference to a list of smtp servers, so if your main server is down, the module tries the next one. If one of your servers uses a special port, add it to the server name with a colon in front, to override the default port (like in my.special.server:2525).
Default: localhost.
From address used if you don't supply one in your script. Should not be of type 'user@localhost' since that may not be valid on the recipient's host.
Default: undefined.
Set this to 0 if you don't want any automatic MIME encoding. You normally don't need this, the module should 'Do the right thing' anyway.
Default: 1;
How many times should the connection to the same SMTP server be retried in case of a failure.
Default: 1;
Number of seconds to wait between retries. This delay also happens before trying the next server in the list, if the retries for the current server have been exhausted. For CGI scripts, you want few retries and short delays to return with a results page before the http connection times out. For unattended scripts, you may want to use many retries and long delays to have a good chance of your mail being sent even with temporary failures on your network.
Default: 1 (second);
Normally, your time zone is set automatically, from the difference between "time()" and "gmtime()". This allows you to override automatic detection in cases where your system is confused (such as some Win32 systems in zones which do not use daylight savings time: see Microsoft KB article Q148681)
Default: undefined (automatic detection at run-time).
Port used when none is specified in the server name.
Default: 25.
Prints stuff to STDERR. Current maximum is 6, which prints the whole SMTP session, except data exceeding 500 bytes.
Default: 0;
use Mail::Sendmail;
print "Testing Mail::Sendmail version $Mail::Sendmail::VERSION\n";
print "Default server: $Mail::Sendmail::mailcfg{smtp}->[0]\n";
print "Default sender: $Mail::Sendmail::mailcfg{from}\n";
%mail = (
#To => 'No to field this time, only Bcc and Cc',
#From => 'not needed, use default',
Bcc => 'Someone <him@there.com>, Someone else her@there.com',
# only addresses are extracted from Bcc, real names disregarded
Cc => 'Yet someone else <xz@whatever.com>',
# Cc will appear in the header. (Bcc will not)
Subject => 'Test message',
'X-Mailer' => "Mail::Sendmail version $Mail::Sendmail::VERSION",
);
$mail{Smtp} = 'special_server.for-this-message-only.domain.com';
$mail{'X-custom'} = 'My custom additionnal header';
$mail{'mESSaGE : '} = "The message key looks terrible, but works.";
# cheat on the date:
$mail{Date} = Mail::Sendmail::time_to_date( time() - 86400 );
if (sendmail %mail) { print "Mail sent OK.\n" }
else { print "Error sending mail: $Mail::Sendmail::error \n" }
print "\n\$Mail::Sendmail::log says:\n", $Mail::Sendmail::log;
Also see http://alma.ch/perl/Mail-Sendmail-FAQ.html for examples of HTML mail and sending attachments.
Experimental SMTP AUTH support (LOGIN PLAIN CRAM-MD5 DIGEST-MD5)
Fix bug where one refused RCPT TO: would abort everything
send EHLO, and parse response
Better handling of multi-line responses, and better error-messages
Non-conforming line-endings also normalized in headers
Now keeps the Sender header if it was used. Previous versions only used it for the MAIL FROM: command and deleted it.
See the Changes file for the full history. If you don't have it because you installed through PPM, you can also find the latest one on http://alma.ch/perl/scripts/Sendmail/Changes.
Look at http://alma.ch/perl/Mail-Sendmail-FAQ.html for additional info (CGI, examples of sending attachments, HTML mail etc...)
You can use this module freely. (Someone complained this is too vague. So, more precisely: do whatever you want with it, but be warned that terrible things will happen to you if you use it badly, like for sending spam, or ...?)
Thanks to the many users who sent me feedback, bug reports, suggestions, etc. And please excuse me if I forgot to answer your mail. I am not always reliabe in answering mail. I intend to set up a mailing list soon.
