Hi community
Got this Client host rejection from a user, that I cannot solve!
Dec 9 15:15:48 server postfix/smtpd[1643]: NOQUEUE:
reject: RCPT from 62.169.86.129.rev.optimus.pt[62.169.86.129]: 554 5.7.1<62.169.86.129.rev.optimus.pt [62.169.86.129]>:
Client host rejected: Access denied; from=<user1@domain.com> to=<user2@domain.com> proto=ESMTP helo=<10.50.106.233>
(emails are fake! the rest is real)
Got an average of 50 to 70 emails rejected only from this single user (sender).
Debugging ...
#1 - This user user1@domain.com is not sending anymore any emails to this user2@domain.com
#2 - He is using an email client (thunderbird) and his machine has no Virus or Trojans what so ever!
#3 - I've temporary disabled his account in iredadmin panel, but rejects still happen.
#4 - I've clean all mail queue (mailq is empty)
#5 - I've created a hash in main.cf smtpd_recipient_restrictions = .... check_sender_access hash:/etc/postfix/sender_access
domain.com OK
user2@domain.com OK
#6 - in /etc/mail/spamassassin/local.cf I've added whitelist_from_spf *@domain.com
Here's my postconf -n output: http://tny.cz/13d22dfa
Here's my master.cf output: http://tny.cz/9ace4e31
Any more info to debug it, let me know !
Thanks for helping and support
