Please explain .com and .co.uk and error message

Sent an email today and it bounced, no such address xxxx.com Strange, someone I email a lot. Sent it again... all same address, and this time no error message. OK then, still puzzled looked back and find their .co.uk address has somehow changed in my "contacts" to a .com address. Nothing I have done ! But resending (still on the "wrong" .com) and no error message.
So what's the difference anyway ? I tried emailing myself putting mine as a .com instead of .co.uk and it seemed OK.

.COM and .CO.UK are totally different domain names and not interchangeable.

However, someone could register both domain names and then set one up as a redirect to the other, so that it didn't then matter which address mail was sent to.

Thanks for explaining that...
I can't explain what has happened to me. This person has a .co.uk address. So a few weeks back I added it to "contacts" (with bt yahoo)one click does it automatically and thought no more of it. When I look now in contacts though it's set itself up as a .com

When I had a breathemail account my e-mail address ended in .net although .com would also work with no interference from me. I therefore concluded that breathe automatically forwarded mail to either account to my default e-mail address.

When someone sets up an e-mail account in Outlook you have the option of entering a return address. If that person actually puts .co.uk into that field it will appear in the header of the e-mail sent to you when in actual fact the default, given my first paragraph, was in fact .com.

That`s my theory!

Thanks... think I understand.

BT Yahoo do appear to have both the "CO.UK" and "COM" addresses (with "CO.UK" redirecting to "COM"), so it may not matter which you used in an email address.

You could check if the same applies to your recipient's domain by checking the websites:

www,domain_name,co,uk

www,domain_name,com [replace "commas" with "dots"]
