Dear Frank, Thanks a lot for responding. I am now reading through the net and trying to implement things as suggested. Just a few queries:
1) As I am interested in sending bulk mails, I am contemplating modification of my DNS zone file with SPF record. Some articles in the net talk about reconfiguration of Postfix for SPF. I believe it is required only when I test the incoming mails for the corresponding SPF records. Am I correct in my understanding? 2) Can you indicate some reliable website to get the dkim-milter package for my RHEL 3.8? 3) Instead of using the mailing list software, for the time being I am planning to use php classes like phpmailer and advice my script to delay for say 5 seconds before sending a mail. Do you foresee any issues in this approach? Sorry for bothering you lots of questions. With regards, Goutam
