We are running cron job to send mail sometime it sends the mail, sometime it doesn’t. Not able to figure out seems it is not consistent.

SUCCESS

  • What does the operator of the next relay say about the 5.6.0 Data format error message? One conceivable scenario would be that the destination refuses to accept well-formatted messages merely because they have (semantically) empty (MIME) body (size=2282 including all local headers might not be much content at all), does your cronjob do that?

  • Thank you @anx . As you can see when the size is more also(case 3) it is still failing. I ve added few more data to case#2 . Could you pls suggest. Jfyi this is a japanese lang system..I was suspecting due lang=c might be causing this issue but on the same day it sents other mails to same server. So I ruled out that one..

    Grab a full copy of such message. Maybe there is an obvious error with the envelope address or header structure. Commented Feb 7 at 20:24
