Thanks for the replies, I also remember seeing couple of times on yahoogroups logs a log entry like "soft bounce, no MX record" or something like that for an account at hasdemir.com domain. One last question, Can I do adding the MX record or is it the web hosting company who is supposed to do that. I will argue according to this information ;) I will also try reaching the postmasters of the problematic domains. thanks again, baris On Thu, 5 Dec 2002 17:44:52 -0500 Chuck Homic wrote:

I have a domain(hasdemir.com) hosted on linux by a web hosting company. Nowadays many emails that I have sent, neither bounce back or be received by the other company. Help desk of the web hosting company told me that probably there are filters for our network (by the way I have no idea on what network means here).
Baris, I did a quick lookup of your domain ('host hasdemir.com') and I didn't get any MX record.
Many SMTP hosts do a lookup of the sending host/ip, and reject mail if it is not an MX, presuming that it's not a "real" mailserver. (This is to prevent spamming from DUL or cable modem links and whatnot.)
I'm on the fence as to whether or not that's a reasonable practice... but it's there. I'd suggest adding an MX record to your domain's DNS. (Whether or not this is the ACTUAL problem you're having at the moment.)
