Problem sending email to certain domain...sometimes....
Intermittently I am having trouble sending email to a certain domain. The email appears to get sent, and then 24 hours later comes back. This happens with mail sent from my ISP and Yahoo.
The IP address is 69.73.182.72
Is there a way I could check connectivity to this address from different geographic locations? I can ping it without problem, making me think the problem is somewhere else?
Failing this, would you guys be able to test if you can ping/tracert it and post if you can and your location, Im guessing that somewhere there is a bad DNS record or something......

Ahh, I see what you mean, nice and ambiguous.
You could check the route is reliable using something like WinMTR (http://winmtr.sourceforge.net/), if you get a lot of dropped packets at certain points in the route then it might indicate a problem.
Otherwise you can check their configuration using a site like www.dnsreport.com (against their domain name), that'll run some basic tests of the mail services.

Thanks for this, it did come up with some errors that Ive sent to the web host.
Ive also set up a test email account ( eetest@icharter.org ) , could you guys send a test email to it and I can check if it gets delivered. If you get a bounce back message (it usually comes 24 hours later) could you post it here for analysis
Many thanks,

Also, you can view the dns report at http://www.icharter.org/dnsreport.pdf
Anyone see anything obvious?

Well there's the lack of RFC compliance, never a good sign when you have to make so many different mail systems talk to each other.

is the lack of reverse DNS a serious issue?
It can be, quite a large number of systems (including Hotmail, AOL, etc) will reject mail if it's sent from a system without a correct set of DNS records.

but that wouldnt affect mail being received? The main problem here seems to be that various smtp servers dont seem to be able to connect to the IP address of the icharter.org mail server.
No, Reverse DNS won't effect that system receiving mail from other sources.
From the places that can't connect, can they route all the way there? Or is that something you wouldn't be able to check?

I dont think I can check that, the first place is smpt1.bethere.co.uk. the smtp server, dnsreports also couldnt connect.
I seem able to connect with that IP address withouth problem. That said, if anyone on here has sent any test messages, I haven received them
