Exchange2000 to Linux based

[tickticker]

exellent responses,

This client is aware that calendaring and other exchange 'features' will go 
bye-bye.  I proposed this as simple pop mail, just send and receive.  there 
are about 10-15 domains receiving mail on this server and I don't think that 
will be an issue.

As for ldap, I concur that this is the way to go, but that is also because of 
other issues (programmability being one important one) They also have an 
AS/400 that must stay and they want the as/400 logon to also autocreate the 
mailbox.  they have several competent as/400 and php/asp programmers on hand.  
I don't need to know how the autocreate function will work, just that it's 
relatively easy to implement.  With LDAP that shouldn't be a problem.  I'm 
more concerned with saving the email that is in the inbox (I could just have 
them all download what is up there and if it's not downloaded, it must not be 
important enuff to keep and the bofh in me will have fun deleting a couple 
gigs of email), and NOT having to manually add the user accounts from the get 
go and automate it after that.  I will investigate the tools mentioned.

Thanks for the help,

anthony
