Issue or symptom
After migrating a mail server from a PowerPC-based server to an Intel-based server, or vice-versa, POP and IMAP services may not work and various "DBERROR" messages may appear in the system.log file. This can happen in Mac OS X Server version 10.4, 10.5, or later.
Solution
-
Make sure that POP and IMAP are not running on the mail server.
- Delete the deliver.db file located in the directory specified by the "Database location" field in Server Admin (the default location is /var/imap/db).
- In Server Admin, click the Advanced tab, then click the Database pane.
- Delete the contents of the db directory located in the directory specified by the "Database location" field in Server Admin (the default location is /var/imap/db).
Note: Do not delete the db directory itself, only its contents.
