Recently I’ve had to migrate some mail servers from old aging SMI E-Smith boxes to newer CentOS boxes running a mixture of Qmail + Vpopmail + Dovecot.\u00c2\u00a0 Now this write up is not going to cover the inital qmail\/vpopmail\/dovecot setup so, if that’s what you’re looking for… Sorry you haven’t found it.<\/p>\n
The primary problem is that the older E-Smith boxes store mail in the following manner:<\/p>\n
\/home\/e-smith\/files\/user\/USERNAME\/Maildir<\/p>\n
*AND*<\/p>\n
\/home\/e-smith\/files\/user\/USERNAME\/Mail<\/p>\n
All your folders and such are kept in the ‘Mail’ folder while all your new mail \/ inbox is kept in the ‘Maildir’ folder.\u00c2\u00a0 Why they did this… I don’t know.<\/p>\n
Anyways, here are the scripts:<\/p>\n
maildir_to_dovecot.sh – This script rsyncs the old data over and then renames it to .Folder.subfolder.etc.<\/p>\n
mailbox=$1 ########################################################## if [ -z “$1” ]; then ########################################################## rsync -av rsync:\/\/$oldhost\/home\/e-smith\/files\/users\/$mailbox \/home\/vpopmail\/domains\/$domain\/$mailbox<\/p>\n ########################################################## cd \/home\/vpopmail\/domains\/$domain\/$mailbox TMP=\/tmp\/$$.tmp ########################################################## cd .. ########################################################## cd Maildir ########################################################## cd .. <\/p>\n Now, we’ve moved everything over and rebuilt the directory structure along with the subscriptions file.\u00c2\u00a0 The issue here now is that all folders appear as a subfolder of ‘Mail’<\/p>\n To fix that I quickly wrote up fixmaildir.sh which is the following: This will move the folders out from under Mail and to the top level.\u00c2\u00a0 This should be executed from *inside* the users ‘Maildir’ (\/home\/vpopmail\/domains\/DOMAIN.TLD\/USER\/Maildir).<\/p>\n Done!<\/p>\n","protected":false},"excerpt":{"rendered":" Recently I’ve had to migrate some mail servers from old aging SMI E-Smith boxes to newer CentOS boxes running a mixture of Qmail + Vpopmail + Dovecot.\u00c2\u00a0 Now this write up is not going to cover the inital qmail\/vpopmail\/dovecot setup … Continue reading
