Hello Eric,

that part of chkuser code is well working and stable, and I do not see
code problems; that error code means simply DNS is not answering.

I've not understood:

  * if problem is on sender or recipient (to know which domains have
    problems).
  * if error is immediate or delayed (to know if there are DNS loops on
    local domain or external domains)


About disabling chkuser, I'd try:

    Enable (uncomment) the following define, and set it to 'RELAYCLIENT'.

        #define CHKUSER_DISABLE_VARIABLE "RELAYCLIENT"

So, if RELAYCLIENT is set, chkuser should not work at all for that session.

Hey Tonino,

Glad you're still with us. :)

QMT has CHKUSER_SENDER_MX disabled, so this must be coming from the CHKUSER_RCPT_MX routine. This is a message which is being submitted, so I'm presuming it's an external domain (although it could be a domain that's hosted locally, or perhaps intra-domain). Vivek hasn't specified this.

I guess we'll need to just wait to hear back from Vivek regarding this and other questions.

Thanks!
