[BlueOnyx:09570] Re: certain email doesn't arrive for a particular domain

[John Kelly]

It might be a stab in the dark here, but there isnt any form of greylisting
in place re receipt of email ??

Greylisting works, except when a major ISP decides if it cant deliver mail
on the first attempt to pass it onto another sending server... Telstra
(Australia's) BigPond (often referred to as PigBond) is a major silly player
in this - I had to whitelist a range of their non sequential IP's
particularly for their wireless internet service so mail could be
delivered....   Might be an idea to check with your uplinks and your own
server re greylisting if it is there..

I agree - but when I use my own ISP this problem occurs.
I have tried sending from a different computer, also.
There could be some DNS problems with a multitude of IPSs but this
particular set of circumstances is not one that I've personally ever seen.

Hi Adam,

Yes, I understand that. That's why I wrote: "Is your client's office server
"looking" at the same nameservers as the SMTP server at your ISP?"

Ken Marcus made the same assumption just some moments ago.

But it still would be wise to also have a look at the logs on your clients
server if you have access to that machine. The mails have to end up
somewhere.......
