Greetings, Sending and receiving emails from the localhost works, but sending email from the local network clients via IMAP/POP gives the following and email rejects, if I add the client IP address to the hosts files works ok, but clients on the local network setup with dynamic ips.
I want to bypass local network DNS lookup, I included my exim.conf setup below. What am i missing? Thanks in advance. 2010-08-03 20:37:55 1OgSva-0000f6-QB H=([192.168.0.7]) [192.168.0.7] F=<[email protected]> temporarily rejected after DATA: Greylisted <<[email protected]>> from <[email protected]> for offences: Host 192.168.0.7 lacks reverse DNS I have the following setup Local Network 192.168.0.0/24 Linux Fedora 13 Exim 4.72 Dovecot IMAP/POP domainlist local_domains = @:localhost:dsearch;/etc/exim/virtual domainlist relay_to_domains = hostlist relay_from_hosts = 127.0.0.1 : 192.168.0.0/16 host_lookup = * begin acl # This access control list is used for the MAIL command in an incoming # SMTP message. acl_check_mail: # Hosts are required to say HELO (or EHLO) before sending mail. # So don't allow them to use the MAIL command if they haven't # done so. deny condition = ${if eq{$sender_helo_name}{} {1}} message = Nice boys say HELO first # Use the lack of reverse DNS to trigger greylisting.
