Hello, I have set up a postfix(2.6.6) mail receiving server (customized with three milters (dkim,sid, custom java milter) and two content filters (amavisd, custom java based)).
Is it possible that if someone sends a mail for my postfix and it gets received in a manner that duplicate mails get generated on my side? In what circumstances is it possible and what kind of remedies if any I can put in place to avoid such a thing. I am posting this question because one of the testers posted such an observation and I am unable to verify/discredit his claims by checking the postfix logs. Thanks in advance Ashish Sharma
