Thanks to those that > might respond. I use a very similar setup (sed -e s/sendmail/exim/g yourmail), and it works just fine. Can't help with point 2, as I am not a sendmail person. But, point 3 - as you are on ADSL, your best bet would be to use dynamic DNS - one thing I noticed about BT's ADSL is that each time you reboot, you are likely to get a new IP address. Create an account on something like ZoneEdit.com (free for up to 5 hosts, I think), and make sure that as part of your startup you update your A record to show your new address. ZoneEdit.com updates are done over http, so you can use wget for this. The problem with using your ISP's name servers is that they will have unsuitable TTL and refresh values for a host whose address is likely to change on a frequent basis. Running your own primaries locally would have problems too - chicken and egg style of thing - how will you advertise your name server, if its IP address is not guaranteed to be the same from one day to the next? If I have misunderstood your question, forgive me - and help me by restating it!
