Did an upgrade this evening from the Ubuntu 8.04 5.0.7 community build on sourceforge to 5.0.9_GA_2533.UBUNTU8 FOSS edition. After the upgrade I couldn't send any messages from the web UI or through IMAP/SMTP. Reading messages worked fine.
Narrowed it down to the following files:
Aug 19 23:23:04 mail postfix/proxymap: fatal: open /opt/zimbra/conf/ldap-scm.cf: Permission denied
Aug 19 23:24:05 mail postfix/proxymap: fatal: open /opt/zimbra/conf/ldap-vam.cf: Permission denied
They had permissions set as the following:
-rw-r----- 1 zimbra postfix 445 2008-08-19 23:09 ldap-scm.cf
Setting these files to allow anyone to read them got my server back up and running. 644 probably isn't right, but it's working at the moment. What are the correct owner/permissions for these files?
Not sure if this applies to 5.0.9 Ubuntu 8 in general, or if it was just caused by my strange upgrade path.
Let me know if any more info is needed.
