The hostname sent is taken from the j macro, which in my case is example1.com
PTR record is also mapping my ip to example1.com
If example2.com uses sendmail, the hostname used with helo will be example1.com
If mail is sent out from example2.com and the receiving mail provider checks PTR record for my ip it will map to example1.com
How would this be addressed ?
