Dear All, I did promise to come back and update you after the problem resolved, but before that i am grateful and personally thanking to everyone for their input, efforts & energy.
Dear Markus Falb, i apologies for my statement yesterday, i actually missed the part of your email, undoubtedly the information you sent was very much valuable and helped to resolve the cause. i do not hesitate to accept that i did not know about call back function before your email. Again special Thanks to Reindl Harald & Markus Falb, they made me to understand what i need to do in order to resolve the cause. FOLLOWING HAS RESOLVED THE PROBLEM: 1.) As you all know, that server where i was sending the message to was configured for address verification & having incorrect PTR records. 2.) When it was coming back for address verification, my server was not accepting connection. 3.) Because my server was configured for "reject_invalid_helo_hostname" i have to disable following in main.cf to deliver the mails to that server. reject_invalid_helo_hostname reject_unknown_client_hostname reject_invalid_hostname Thanks / Regards Prabhpal > Dear Markus Falb > > Thanks for your response, it is grate information. it is true i missed the > part of your mails. > > Thanks / Regards > > >> On 12.4.2012 14:16, Prabhpal S.
