I did an update of postfix, dovecot etc. on Feb 22. This worked fine and everything has been running smoothly since.
However, I just noticed these messages in my postfix log: Mar 23 10:43:04 mail smtp/smtpd[70713]: warning: database /opt/local/etc/postfix/aliases.db is older than source file /opt/local/etc/postfix/aliases Mar 23 10:43:04 mail smtp/smtpd[70713]: warning: database /opt/local/etc/postfix/rna_sender_canonical.db is older than source file /opt/local/etc/postfix/rna_sender_canonical Mar 23 10:43:04 mail smtp/smtpd[70713]: warning: database /opt/local/etc/postfix/rna_recipient_overrides.db is older than source file /opt/local/etc/postfix/rna_recipient_overrides Mar 23 10:43:04 mail smtp/smtpd[70713]: warning: database /opt/local/etc/postfix/rna_virtual_users.db is older than source file /opt/local/etc/postfix/rna_virtual_users Mar 23 10:43:05 mail postfix/trivial-rewrite[70715]: warning: database /opt/local/etc/postfix/rna_virtual_domains.db is older than source file /opt/local/etc/postfix/rna_virtual_domains Mar 23 10:43:05 mail postfix/trivial-rewrite[70715]: warning: database /opt/local/etc/postfix/transport.db is older than source file /opt/local/etc/postfix/transport Mar 23 10:43:05 mail postfix/cleanup[70716]: warning: database /opt/local/etc/postfix/rna_sender_canonical.db is older than source file /opt/local/etc/postfix/rna_sender_canonical Mar 23 10:43:05 mail postfix/cleanup[70716]: warning: database /opt/local/etc/postfix/rna_recipient_overrides.db is older than source file /opt/local/etc/postfix/rna_recipient_overrides Mar 23 10:43:05 mail postfix/cleanup[70716]: warning: database /opt/local/etc/postfix/rna_virtual_users.db is older than source file /opt/local/etc/postfix/rna_virtual_users And what seems to have happened is that the MacPorts maintenance has touched the dates on these files (without actually changing them): -rw-r--r-- 1 root admin 12144 Feb 22 13:37 aliases -rw-r--r-- 1 root admin 16384 Oct 4 15:53 aliases.db -rw-r--r-- 1 root wheel 10519 Feb 22 13:37 aliases.sample Hmm, that is not nice. It should leave those files such as my aliases file alone. Probably a fix/check for ownership? Is this something that is fixable in the port or is this something inherent in the way MacPorts work when installing? (Same happened with dovecot. I have been using the mail-server port as an umbrella, so it might have been that one) G
