[IMail Forum] Duplicate HELO/EHLO follow up

Title: Duplicate HELO/EHLO follow up

I have been watching the logs closely and have actually noticed that we are getting this a lot, (this is just one more entry in the log) however most servers just seem to ignore it. Unfortunately the important ones don’t :)

So co-nawa.com just accepts it and gets on with the job.....



This is a response from my server when I telnet to it.

220 X1 NT-ESMTP Server imail.ipc.ac.nz (IMail 6.06 7107-3)
EHLO
502 unimplemented command
EHLO
250-imail.ipc.ac.nz says hello
250-SIZE 0
250-8BITMIME
250-DSN
250-ETRN
250-AUTH LOGIN CRAM-MD5
250-AUTH=LOGIN
250 EXPN

So the first time I send EHLO it says 502 but the second time it accepts it ....

Same thing happens if I open a connection and type HELO

220 X1 NT-ESMTP Server imail.ipc.ac.nz (IMail 6.06 7122-3)
HELO
502 unimplemented command
HELO
250 hello imail.ipc.ac.nz

Seems to be this side that the problem is how do I fix it???
