Hi all. I have a very strange problem with my wife's mail which I am almost embarrassed to post here. Please don't laugh - the problem is real and the question is genuine.
My wife is running Mail 4.5 (1084) under OS 10.6.7 on a MacBook Pro. Our mail provider is Newtel (www.newtelsolutions.com) and our outgoing server is post.guernsey.net, but we are on holiday in Denmark at the moment and are therefore connecting through our Danish ISP, TDC (http://mail.tdc.dk/), still using post.guernsey.net. The account is set up to use default ports (25, 465, 587) and password authentication.
All this normally works well, but in the past week some of her mails to three different recipients have been rejected with the error message "Cannot send message using the server post.guernsey.net."
I have tried other outgoing servers, including TDC's, to no avail. Then, in one of my troubleshooting attempts, I removed a link to her blog which was present in all three mails. As soon as I did that, the mails went without a hitch.
The link in question is: www.linen-and-silk.com. Go ahead and try it, it's perfectly legit and innocent; my wife is a textile artist and her blog is well respected among the quilting fraternity.
I can send mails with this link from my own, separate computer, using exactly the same hardware and software setup. And from her computer I can send mails containing links like www.linen-and-sulk.com and www.linen-and.sill.com (both of which are nonexisent URLs), but absolutely NOT www.linen-and-silk.com. Why on earth not?
It reminds me of the story of the company that could not send mails farther than 500 miles (see http://www.ibiblio.org/harris/500milemail.html). I am sure my problem has an equally pragmatic cause, but can anyone find it?
