Migrate courier and vpopmail to dovecot and vboxadm

Export User

loop through all domains (e.g. /var/vpopmail/domains)

• open vpasswd to get real mailboxes with crypted (MD5) passwd
• look in all mailboxes for a .qmail to get alias
• look in all .qmail- files to get more aliases

result is a vboxadm-command. vboxadm needs to be patched to import the crypted password

vboxadm mailbox add name@domain.de -n 'my name' -cp '{CRYPT}$1$p0cQI5u5$ldfdfdfdfdfma0wLJ.1' --domainadmin 0 -a 1
vboxadm alias add postmaster@domain 'name@domain.de'
