I want to find SMTP service running on a Network . Currently in my application user has to give SMTP server IP address (which is hardcoded). I want to give facility to detect SMTP server IP address automatically. Is there any way to find out the same. Please give some slutn. in advance thx
hi do u know the host name u mean for the SMTP server and want to find IP? (well that doesnt make sense though ) 'coz otherwise knowing nothing we can't probably query where is SMTP server i guess regards maulin
If you want to identify the SMTP servers that service incoming mail to a specific domain, you'll want to query for MX records with a library like DNSJava. Note that when a domain has no MX records, you should try the IP of the domain itself.
