Using Jmeter to test an SMTP server

[Rajendra Gokhale <rv...@gmail.com>]

Hi,

I am trying to use JMeter to generate load on an SMTP server (checking how
many incoming emails the SMTP server can handle).  I have tried connecting
and sending mails using telnet on port 25.  The interaction looks something
like this:

telnet> HELO
successful
telnet> MAIL FROM:foo@bar.com
successful

What is the right way of simulating this interaction using JMeter?  I tried
using two TCP samplers, one for each of the above requests but that approach
fails since the SMTP server considers them as two separate sections.

If I try to send the HELO as well as the MAIL requests in the same sampler,
I get a successful response for the HELO but not for FROM.

As far as I can see, the SMTP server is behaving correctly and my question
is : what do I need to do in order to get this right?

Thanks in advance,

Rajendra Gokhale

JMeter does not support testing SMTP servers.

You'll need to write your own Sampler, or your own TCP implementation.
