Stuck with email	Can't Post

Hi Gurus,

I am new to perl and have a requirement to send email from perl script running on the linux environment. I need to define the 'from' address in the syntax as well. The below command when run on linux works fine:

Code

mail -s subject to_address -- -f from_address

However when i try the same from Perl script using the below code it gives me the error:

Sendmail invalid option -- -f

Code

sub func_sendmail(){ 
        `mail -s "$_[0]" "$_[1]" . "-- -f" .  "$_[2]" < $input`; 
} 
 
func_sendmail("subject","to_address","from_address");

I have also tried the use Mail::Sendmail but even that does not work.

Could someone please let me know how to resolve this.

Thanks in advance!

There are a number of mail modules on the CPAN:

Thanks a lot for the reply! Will definitely go through it. However, i doubt that i have the function written in wrong way or i am not calling it properly because if i type the below statement (not function) in a perl script and execute it, it sends the email:

Code

#!/usr/bin/perl 
use warnings; 
use diagnostics -verbose; 
`echo hello | mail -s subject to@address.com -- -f from@address.com`

Your main problem is improper quoting. I can demonstrate what you re passing to the shell by printing your command.

Code

sub func_sendmail { 
    $input = 'my_mail.txt'; 
    print qq(mail -s "$_[0]" "$_[1]" . "-- -f" .  "$_[2]" < $input); 
    #       `mail -s "$_[0]" "$_[1]" . "-- -f" .  "$_[2]" < $input`; 
} 
func_sendmail ( "subject", "to_address", "from_address" );

There are several other errors.

Always use strict and warnings.

Place subroutine definlition at end of program.

Prototypes do not mean what you think. They should seldom be used.

The function system (refer: perldoc -f system) is a better choice than backticks in this application.

Combining these ideas:

Code

use strict; 
use warnings; 
func_sendmail ( "subject", "to_address", "from_address" ); 
sub func_sendmail { 
    my $input = 'my_mail.txt'; 
    my $cmd = qq(mail -s $_[0] $_[1] -- -f $_[2] < $input); 
    print $cmd, "\n"; 
    my $status = system $cmd; 
    print "Email status = $status\n"; 
}

(untested - I do not have access to linix)
Good Luck,
Bill

Hey Bill,

Thanks a lot, that worked perfectly and thanks for all the suggestions. I will try to implement those in my scripts.

Thanks once again!
