It's worth absolutely making sure that you always set whatever mail client you use to show both the "Sender" - from - and "Reply-To" address, for every email, regardless.
The default - and for most people the default is Outlook, or Outlook Express, or Windows Mail - is to only show the "Sender", and you need to be aware that things are not honest, and that there are lying scamming scum out there that abuse emails and how to look for them. The default seems to be to try and protect ignorant people from the harsh realities of information that might make them think something is wrong, and give them a clue.
Most people won't have a "catchall" email address, so most people won't see all the spam that is directed at their address even if they have their own domain.
eg if I owned the - non-existent, at this point - dominionwibblyfibblywibble.co.uk domain, and had catchall email on that, then you could send an email to thundercatwiblefishcakemadeuprecipient @ dominionwibblyfibblywibble.co.uk
and I'd get that email.
And in lots of cases emails are sent to totally spurious addresses, and they clog up the system or get bounced back to the "faked" sender as an "undeliverable" because the recipient address does not exist.
And to the casual user - 99.9999% (ish) of internet users - that stuff does not even happen, because the network traffic that goes on between mail servers is hidden from them in an ever increasingly consuming battle against botnets and spammers.
phew, rant over!
