Sync'ing Old & New POP3 Servers

[StarTAC]

hi all..

i currently have a POP3 server running on Solaris, and i am building a new POP3 server with added features and support on Linux..

when ready, i'd like to move all the exisiting mail from the Solaris box to the Linux box... i've been thinking about how best to do this, and things like 'rsync' have sprung to mind, but i was wondering whether anyone has a better way of doing it..

my current mail storage format on the Solaris server uses virtual domain mail storage.. e.g.

/var/popusers/example.com/a/a*/Maildir/
/var/popusers/example.org/g/g*/Maildir/
/var/popusers/example.net/2/2*/Maildir/

creating this format on the Linux box won't be a problem, but i wonder how best i can copy existing mail on the Solaris box onto the Linux box, so as to make the transition painless, transparent and smooth for my customers..

all help appreciated..

This is what UUCP is used for. I believe it's a bit complicated to setup although I've never tried.

hmm... i see..

well, i'll give it a read and see wot to do... i can imagine setting up on Linux will be slightly easier than trying to set it up on Solaris..

all help appreciated..

Depending on how many users you have, I found it easiest to open the mailboxes in an MUA and bounce the messages to the new server.

this would be great, but for an ISP, that would be alot of bouncing.. there's quite alot..

all help appreciated..

You might look at fetchmail to iterate over all the users and suck their mail to the new server. It will connect via pop and redeliver their mail on the new server using the local deliver agent.
