However, in the event that I need to reboot the server (perhaps a kernel update was added to Portage), I would like to have a miniature mail server which catches incoming mail if, and only if, my primary server is do= wn. I have Gentoo installation on an old Raspberry Pi (model B+), and was curio= us if such a set-up was possible ? I also want the solution to be as minimal as possible. I see the problem as three parts: (a) Convincing the D.N.S.\ and my router to redirect mail to the alternate server, should the default one not be reachable; =20 (b) Creating the alternate mail server to be as lightweight as possible. I= 'm not even sure if I need an S.M.T.P.\ server (postfix). Would courier-imap = do the trick on its own (with courier-authlib and mysql) ? (c) Moving mail from the alternate server to the main server once the latt= er has regained conciousness. I realise this is a slightly different problem,= and is not even necessarily _required_ for operation, although it's certainly a nice-to-have. What do you think; is this at all possible ? Has anyone here done anything = like this before ? Thanks in advance. --=20 Ashley Dixon suugaku.co.uk 2A9A 4117 DA96 D18A 8A7B B0D2 A30E BF25 F290 A8AA --2diymntgzi66m7d3 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKpralop7ow7ykEEX0Yqw0r8lqKoFAl6LIfMACgkQ0Yqw0r8l qKqo7hAAoXKwNJyv4AGITfDlM0TIsOwLZdRvGHgh59WUEnf9Jo3x0m6FylejNG0F GQse7kx/d62XWN4ltSMppKRNdQ/2HVh5OyZSPpQ86gnsRfCXaI7Fc0qIkRSvotbW d2LdOuVBJUfdOOR8oNRIFIH27LmZZgfePq7AVHT8WdulkhHW3Jiwlt2kLq/kOkB5 xfkMZ7aYGiEu3CltJSzrjEMo9V57hBocIo3h1dE9wksx7NlOKSB1B+sDNttcj5X+ 2a3OlE95OqIt2ilcGOU1RrUWxW8pqT8GaCYWkjpaBNXNOsWNdjFXaG6qujydRROQ MZMZgu16StwkIsVyJiY17Fw046E51nRgRzAyPecs42eW4RFBYklr2xQZyrM8ERn7 GvwHVNOEZ3ocGQLaCB2inC/Gw1MFH7ShxnJVEmy/0lC4JfmDYl/T2CM+sZ8tHK3w xQQvs/K1A++TOZ0IuH+8iKsDhubEtxgISU325GVYVe77SfzPjWMrWXRk6htFRaXU ryr9fGFDUDADm1E3q/9P/WI24qeLwiv4sPDf0avcwxsBBHCocBgBw68eoUBx3A+n hSVD4suLY6GFi8y7d1XOCj5Yx2gNfSa9e09jA5awZiLzGfW+Jl181gHtyai82YW0 aQZZ8ZU+mFGchTgyvgcttpHYq7UePCs6VxCvfFHqR2ztutL0xCk= =Ar1S -----END PGP SIGNATURE----- --2diymntgzi66m7d3--
