Hi all,
Maybe this has been discussed already but I can't find any relevant info.
All our smtp tests sporadically report similar error:
yellow Wed May 17 14:37:21 2006 smtp NOT ok
Service smtp on mailc is not OK : Unexpected service response
554 SMTP synchronization error..
Seconds: 0.00
How can we avoid this?
I made my own SMTP-tester (to test MX for certain domains, not SMTP on
certain hosts) and there I met this problem. My test is as follows
MXTEST=$((sleep 1 ; echo quit) | nc -w 1 ${MXHOST} 25) || MXCOLOR="red"
Without the sleep, some microsoft servers refused to repond 220, and
without the -w 1 for netcat, some exim servers reponded with the above
554. (IIRC, it might have been the other way around)
I dont really understand why the sleep make any difference, but somehow it
does.
