Now you should connect to the same program with 10 connections at
the same time, using the Postfix smtp-source tool.

../smtp-source -c -l 10000 -m 1000 -s 10 -f ashiish.sharma(a)gmail.com -t cp_user(a)dev1.cpgtest.ostinet.net 10.194.99.63:100

The Postfix smtp-source tool is distributed with Postfix source
code, and is sometimes installed by Linux distributions.

Your java filter sent a greeting: "220 Hello\n"
instead of: "220 Hello\r\n". Amavisd waited 30 seconds but
end of line (CR LF) never arrived, so the session was aborted.

RFC 5321 (and RFC 2821 and RFC 821) requires that SMTP commands
and replies are terminated by a CRLF, not by a single LF character.

Then, your custom SMTP code needs to be replaced. To speed up
development, may I suggest that you consider using already-deployed
SMTP code instead of re-inventing your own.

Wietse,

Thanks for your suggestion.

Since I am new in this can you suggest some java based deployments that I can use. I too looked for what you have suggested but maybe I didn't looked hard enough.

Thanks in advance
