Thanks to everyone for your responses.
I think the key issues raised were
1. Danger of bounces due to DNS caching immediately after an IP change.
2. Suggestion that maybe another protocol might be better.
The bouncing problem is maybe enough to stop me doing it. Though the reality
is that the business gets less email than I do here at home so maybe a 10/20
minute potential blind period is livable with. I was half thinking of trying
to script a disconnect/reconnect overnight in an effort to ensure I have a
stable IP during the day, but I am unclear how Eircom are issuing the IP
address - it doesn't seem to have a DCHP lease. I get the impression from
reading on the web that PPPOE connections are liable to change IP at any
Re using another protocol, I looked at taking the mail down with uucp and
then processing it through the mail server. But I assume Eircom need to do
something on their side (uucp account setup? change the way they store my
mail?) and I don't know enough about uucp to even know what to ask them for
So. I am sorely tempted to try it :)
I'll let you all know how I get on if I do.
