So, you have multiple addresses, so could this be a DNS issue that you are not guarenteed to get the right server?

Could this be a firewall issue? Try to open the connection:-
Code:
telnet www.xxx.yyy.zzz 25

for each IP address that the DNS returns. Port 25 is the smtp port. You should get output similar to the following:-
Code:
# telnet www.xxx.yyy.zzz 25
Trying...
Connected to mail.mycomp.com.
Escape character is '^]'.
220 mail.mycomp.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.1830 ready at  Tue, 21 Dec 2010 13:30:58 +0000 
quit
221 2.0.0 mail.mycomp.com Service closing transmission channel
Connection closed.

If not, you could have a firewall issue, or perhaps even be going to the wrong place entirely. If you can ping the address, then a firewall issue would simply seem to hang (timeout in about 30 seconds usually) If you can't ping, then it's DNS or routing I expect.



Do let us know how you get on.

Net::DNS::Mailbox(3)					User Contributed Perl Documentation				      Net::DNS::Mailbox(3)

NAME

       Net::DNS::Mailbox - DNS mailbox representation

SYNOPSIS

	   use Net::DNS::Mailbox;

	   $mailbox = new Net::DNS::Mailbox('user@example.com');
	   $address = $mailbox->address;

DESCRIPTION

       The Net::DNS::Mailbox module implements a subclass of DNS domain name objects representing the DNS coded form of RFC822 mailbox address.

METHODS

   new
	   $mailbox = new Net::DNS::Mailbox('John.Doe@example.com');
	   $mailbox = new Net::DNS::Mailbox('John Doe <j.doe@example.com>');

       Creates a mailbox object which represents the DNS domain encoded form of the mail address specified by the character string argument.

       The argument string consists of printable characters from the 7-bit ASCII repertoire.

   address
	   $address = $mailbox->address;

       Returns a character string containing the RFC822 mailbox address corresponding to the encoded domain name representation described in
       RFC1035 section 8.

DOMAIN NAME COMPRESSION AND CANONICALISATION

       The Net::DNS::Mailbox1035 and Net::DNS::Mailbox2535 subclass packages implement RFC1035 domain name compression and RFC2535
       canonicalisation.
