not well. It works fairly well for a small number of mailboxes, but it doesn't scale well. The last time I had a similar problem (a few years ago), I setup mailboxes elsewher e(at fastmail.fm that time) and then used imapsync to pull the mail down to the local mailstore. using fetchmail to then deliver it to the SMTP server so that it goes through the filtering mechansims that are in place would be one step better, but these are significantly more clumsy to use than the UUCP approach was. With the UUCP approach my users didn't care that they had intermittent network access, (I used diald to bring up the outbound connection whenever anyone needed it) the only symptom that they could see is that sometimes e-mail took a bit longer to arrive. This was a lot more work to setup, and so now that I'm out of crisis mode (but still thinking about it), I want to figure out how to best handle this in the future and document it so that I just have to do it rather than figure it out when things break in the future :-) I would expect that this would be useful for other people who are in areas where they have less than reliable data connections (people running on generator power, or with expensive per-minute satellite connections say on ships, etc) David Lang > [email protected] wrote: > >> On Fri, 22 Oct 2010, Nathan Hruby wrote: >> >>> On Fri, Oct 22, 2010 at 4:36 PM, <[email protected]> wrote: >>>> I just suffered an outage to my home Inernet server that looked like >> it >>>> was going to last for a week or so, and started to scramble to >> figure out >>>> how to set something up so that my home mail server (which could >> reach the >>>> Internet via a cell card) could receive e-mail.
