SendMail Function Failure
Hi All,

Background: We use SendMail function (given below) to send emails to users. The email address are obtained as ouptut of a stored procedure in sybase.

We have defined a SendMail function as below in a .pm file and it is used in a .pl script.

Code Snippet:
Code:
sub SendMail
{
    my (
         $Message ,
         $Subject ,
         $To,
         $CC
       ) = @_;
    my ($sec, $min, $hour, $mday, $mon, $year) = localtime(time) ;
    my $PgmName = "$hour:$min:$sec" ;
    Log( "\nRecepients To: << $To >>\n" ) ;
    Log( "\nRecepients CC: << $CC >>\n" ) ;
    open(SENDMAIL, "|/usr/lib/sendmail -oi -t")
        || die "Can't fork for sendmail: $!\n";
#Content-Transfer-Encoding: quoted-printable
    print SENDMAIL << "EOF";
From: $MAIL_FROM
Date: $PgmName
To: $To
CC: $CC
Subject: $Subject
Content-Type: text/html; charset="iso-8859-1"
$Message
EOF
close(SENDMAIL) || die "sendmail didn't close nicely";
   if( $? !=0  )
   {
      Log("System Mail Failed");
   }
   else
   {
      Log ("Mail Sent Successfully");
   }
}

The above SendMail is called in a perl script.

Issue:

Lets say we have 10 email address to which emails has to be send, and the 5th email address's mail box is no longer available though the email address is a valid one. Henceforth the sendmail function fails with "
sendmail didn't close nicely " message and email is not send to the rest of the people.

Expected Resolution Options

i) Validate whether the mailbox is still active. OR
ii) Prevent the sendmail from failing & continue to send the mail to the other people.

Kindly provide a possible solution. Thanking All in advance for your time.

posix::strptime

POSIX::strptime(3pm)					User Contributed Perl Documentation				      POSIX::strptime(3pm)

NAME

       POSIX::strptime - Perl extension to the POSIX date parsing strptime(3) function

SYNOPSIS

	($sec, $min, $hour, $mday, $mon, $year, $wday, $yday) = POSIX::strptime("string", "Format");

DESCRIPTION

       Perl interface to strptime(3)

FUNCTIONS

       strptime
	    ($sec, $min, $hour, $mday, $mon, $year, $wday, $yday) = POSIX::strptime(string, format);

	   The result for any value not extracted is not defined. Some platforms may reliably return "undef", but this is dependent on the
	   strptime(3) function in the underlying C library.

	   For example, only the following fields may be relied upon:

	    my ($min, $hour) = ( POSIX::strptime( "01:23", '%H:%M' ) )[1,2];

	    my ($mday, $mon, $year) = ( POSIX::strptime( "2010/07/16", '%Y/%m/%d' ) )[3,4,5];

	   Furthermore, not all platforms will set the $wday and $yday elements. If these values are required, use "mktime" and "gmtime":

	    use POSIX qw( mktime );
	    use POSIX::strptime qw( strptime );

	    my ($mday, $mon, $year) = ( POSIX::strptime( "2010/07/16", '%Y/%m/%d' ) )[3,4,5];
	    my $wday = ( gmtime mktime 0, 0, 0, $mday, $mon, $year )[6];
