I have one courier box with about 3000 mailboxes, username/password of users re stored in mysql table (with encrypt() function for password).
I wish to migrate those mailboxes to cyrus-imapd by using imapsync. The problem is I dont know the user's password !
So I want to create another instance of couriertcpd which uses another authmysqlrc (will point to another column password) and listen on another port than 143, e.g 144 for example --> this instance will be used to sync mail to cyrus.
I am newbies in courier, that box was setup by another guy in my department, but now he change to a difference department.
I hope you pro can help me. Here is my running courier instance :
/usr/lib/courier-imap/libexec/couriertcpd -address=0 -maxprocs=300 -maxperip=500 -nodnslookup -noidentlookup 143 /usr/lib/courier-imap/sbin/imaplogin /usr/lib/courier-imap/bin/imapd Maildir
Thank you very much.
