Hello
I want to know is there any site or resource on Internet which lists all the commands of SMTP/ESMTP and SMTP/ESMTP error codes.
Dear Komal,
The best place always for all the standards is the RFC Repository.
http://www.faqs.org/rfcs/rfc2821.html
Are you planning to create a SMTP server? :)
Paul
Thank you
Regards,
Komal
