I know that

Code:
sendmail -bv email@address.com

can do it but there is a compatibility issues with the version of Unix we have. So mailx is the only command we can used at this point.

Any pointers in this regard will be appreciated. Smilie

May be
Code:
telnet address.com
EHLO address.com
VRFY email

?

NAME
Mail::Verify - Utility to verify an email address SYNOPSIS
use Mail::Verify; DESCRIPTION
"Mail::Verify" provides a function CheckAddress function for verifying email addresses. First the syntax of the email address is checked, then it verifies that there is at least one valid MX server accepting email for the domain. Using Net::DNS and IO::Socket a list of MX records (or, falling back on a hosts A record) are checked to make sure at least one SMTP server is accepting connections. ERRORS
Here are a list of return codes and what they mean: 0 The email address appears to be valid. 1 No email address was supplied. 2 There is a syntaxical error in the email address. 3 There are no DNS entries for the host in question (no MX records or A records). 4 There are no live SMTP servers accepting connections for this email address. EXAMPLES
This example shows obtaining an email address from a form field and verifying it. use CGI qw/:standard/; use Mail::Verify; my $q = new CGI; [...] my $email = $q->param("emailaddr"); my $email_ck = Mail::Verify::CheckAddress( $email ); if( $email_ck ) { print '<h1>Form input error: Invalid email address.</h1>'; } [...] perl v5.8.8 2002-06-09 Mail::Verify(3pm)
