* please do not reply off-list
* please provide real log without "smtp.ip.add.ress"
* please do not top-post (i refuse to fix the thread)

usually your host has a PUBLIC hostname
usually your host is using this as myhostname = HELO
usually the PTR to your ip should have the same name
usually you need to have a valid PTR

these are the only things you should care on a public mail-server
________________

with "mail2.localdomain" as HELO as example we would never
accept any message from you because properly configured
mailservers would not do this

smtpd_helo_restrictions:
 * reject_non_fqdn_helo_hostname
 * reject_invalid_helo_hostname
 * reject_unknown_helo_hostname

smtpd_recipient_restrictions:
 * reject_invalid_hostname
 * reject_unknown_reverse_client_hostname
