So, did you just say, that you check mail for one account (you mentioned
a single ISP only) from two different places, namely home and work? That
scenario spells IMAP to me -- your *own* IMAP server at home.
That way, you will need a single SA only, and a single server to
maintain.
Well, I hadn't really expected to find anyone on the list who is
willing to be so helpful, but since you are . . . :)
Basically, your understanding of my description is correct. Of
course, my own first thought when I started thinking about this was
precisely what you just suggested. The problem with that is that I am
with one of the big commercial ISPs (Comcast), and I don't have a
static IP address, so I can't point to my router from any arbitrary
machine on the internet. I do believe that I can do some kind of
dynamic DNS with my router. Then I can probably pass incoming
connections to port (whatever for imap) through to my home machine.
At some point, it just seems that the "right" solution is too much
hassle, so I was just looking for a lower energy solution.
A lot of people have gotten home mailservers running on so-called
"dynamic" IP addresses - when they have discovered that Comca$t will
continually approve DHCP re-lease requests for the same IP address.
Often people can go for 4-6 months at a time with the same
"dynamic" IP address if the gear is on a UPS
Just setup your stuff, get an IP number, then query DNS and see
what the PTR record for the IP address is, then name your server
the same as that PTR name, and in DNS setup that name as an MX
host.
If the IP changes then modify the hostname to the new PTR name and
modify the MX in DNS and restart the mail process on the mailserver.
Of course you can do the dydns.org route but then your PTR will
not match the hostname and some servers out there will not accept
mail from you if that is the case.

I could completely believe that the solution I came up with might have
some fatal flaw, but I thought I would give it a shot first . . .
