right, so I need to create an A record for mail.domain.co.uk on my home server?

And then set the mx record with 1&1 to mail.domain.co.uk?

What would the email address be? anything@domain.co.uk, or anything@mail.domain.co.uk?

assuming the 'anything' can actually be anything since the smtp should put it all in the same folder?
The a record needs to be on your authoritative dns (likely to be same place as where you put MX record

You cannot recieve mail without furthr software, as it has to be delivered to a mailbox.


Cant find anywhere to add an A record  :-?
Might be called HOST record.

If I select 'domain.co.uk' and click DNS settings, all I get is IP Address (A-Record) - All I can type in here is an IP.

And Mail Exchanger (MX-Record) - for MX 1 / Priority (4 of)

Thats it. So the A record is my servers IP - It always has been. So if I type in mail.domain.co.uk in the MX record, how does that link to my server? Or will 1&1 somehow change that to mail.123.123.123.123? where 123=my servers ip.

Think im getting my wires crossed somewhere  :'(
Thats right - the relay sending to you firstly looks up MX for mydomain.com, which it gets back a normal DNS name, which it then attempts to connect to (doing a 2nd dns lookup to convert to IP).

The freeware software providing mailboxes will most likely do the receiving, rather than IIS's SMTP.  IIS SMTP isn't really a full blown, robust relay.

mail queue would be due to open relay, but it was unable to relay at that time (probably because its relayed millions ;D).  bad mail is stuff it cannot or does not want to deal with (usually destined for your domain, but no mailbox to put it in).
