Please forgive the top posting, this is difficult with a blackberry. The log snippit shows..:
fileserver.test.org192.168.1.31]:25 You you have a transport file or relayhost setting? It might have a problem with a typo I can see a closing square bracket, but not an opening square bracket.

Postfix version 2.6.6 on both host and guest. Host OS RHEL server 6.0 Guest OS RHEL server 6.0 Virtual Machine QEMU-KVM Host has 2 virtual interfaces virbr0 and virbr1 Postfix (guest and host) is listening on all interfaces. IPTables IS NOT RUNNING on either guest or host. DNS Lookup is turned off on both host and guest. I want to send mail to host from guest. Ping both host interfaces work Telnet to port 25 from guest to either host interface also works just fine [root@guestServer init.d]# telnet fileserver 25 Trying 192.168.1.31... Connected to fileserver. Escape character is '^]'. 220 fileserver.test.org ESMTP Postfix HELO guestServer 250 fileserver.guest.org I get the following when trying to send mail. Nov 6 09:44:41 guestServer postfix/qmgr[14456]: DD94E63D92: from=<r...@guestserver1.test.org>, size=464, nrcpt=1 (queue active) Nov 6 09:44:41 guestServer postfix/error[14507]: DD94E63D92: to=<bl...@fileserver.test.org>, orig_to=<blair@fileserver>, relay=none, delay=553, delays=553/0.01/0/0.31, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to fileserver.test.org192.168.1.31]:25: Connection timed out) As I said before IPTables for both ipv4 and ipv6 are not running. I have tried configuring for just ipv4 same results. All posts suggest looking at firewall, but iptables is not running. Many thanks in advance. Rick -- Tìoraidh! Rick Blair
