    Default [SOLVED] Lost Connection with one domain

    Alrighty, bear with me as I'm still a little new to this stuff.

    Release 5.0.9 FOSS on Ubuntu 8.0.4

    Everything has been working since I set this up month ago. Send and receive just fine. I'm testing Zimbra. Monday I tried renaming the domain using "zmprov -l rd duratechind.com duratechindustries.net". That worked, and I was able to send and receive just fine. Then yesterday I renamed it back to what it was, and now I can't send e-mail to one particular domain. E-mail to lwinstead(at)daktel.com get's deferred with the error "lost connection to inboundmail2.daktel.com[66.163.144.16] while sending rcpt to".

    I read lots on the forums about not being able to send out at all, but I AM able to send out to other domains, just not that one. Can someone help me figure out how to diagnose this?

    By the way, according to what I've seen, my /etc/hosts file is fine, /etc/resolv.conf is fine, and the dig commands come back legit. The "host `hostname`" command has never worked as expected, but even still I have been and still am able to send and receive to other domains. Argh.

    Send a email to postmaster(at)daktel.com and ask them why your connection is being dropped

    Alright, I've figured it out.

    I should have done this right away, but I panicked and lost my head. After doing everything I could to figure out what was happening (see below), I finally decided to try to telnet to that inboundmail2 server and manually send e-mail out. Lo and behold, I get a clear message following the "rcpt to" command that tells me I'm being blocked by Barracuda because of my reputation with them. So I called up Daktel, who is my ISP and who owns that inboundmail2 server, and they helped me out. They requested to Barracuda that I be delisted. All I have to do now is wait for that request to propagate to this particular Barracuda device (or all of them, really).

    SOLVED! The only question left is: What on Earth did I do to get listed?! Ugh...
