This is so cryptic, what does it all mean? You may use more than one DNS server -> it may produce "non static" response patterns. As I understand WorkAroundBrokenAAAA is intended to "fix" replies from broken DNS servers (caches) that return "temporary problem/try later" instead of "no AAAA record". > Since getting dovecot to work with sendmail, I am now receiving email on > my Windows machine from the Linux machine like this now (I tried to send > a test mail ito myself at my ISP from Evolution): > > ********************************************** > ** THIS IS A WARNING MESSAGE ONLY ** > ** YOU DO NOT NEED TO RESEND YOUR MESSAGE ** > ********************************************** > > The original message was received at Wed, 3 Feb 2010 22:02:51 -0500 > from localhost [127.0.0.1] > > ----- Transcript of session follows ----- > <theohmster(a)comcast.net>...

It works quite well in Windows Live Mail and it worked with Sendmail before in Fedora 6. Since putting in a new hard drive and installing Fedora 12, this is the problem I am having now. BUT, and this is a big one, I did not have this POS Motorola router in front of the Fedora box. Well I did have a nice Linksys but I had it run not as a DHCP server, just as a wireless point of origin and as a Vonage phone device. The router had put the Linux box in the DMZ and was pretty transparent. The Linux box did act as a router, it had a 2nd NIC, ran a firewall, DHCP server, and IPv4 forwarding. This time around, the router comes first, does the DHCP serving, and is a bit hard to configure. But in answer to your question, I have never had to do that before, smtp works with Live Mail, and I like to use the domain that they give me so if they change their servers around, the mail should still work. -- ~Ohmster

Well maybe, but Comcast does not recommend that, it works with other mail programs like Live Mail. I think that is so that they can move the server to any IP address or machine they like, all they have to do is change the DNS on it and you will always be able to find "smtp.comcast.net". Only problem is, that in this case, it does not seem to be working. I had thought about just putting in the IP address of the server itself but for the reason stated above, I did not do it. -- ~Ohmster | ohmster59 /a/t/ gmail dot com Put "messageforohmster" in message body (That is Message Body, not Subject!) to pass my spam filter.
