I have installed Zimbra 5.0.0_GA_2201 on a Debian 4.0 box, and I'm having an issue with all of my incoming emails being deferred. I've checked the IP configuration and DNS can resolve correctly to both the NS, MX records, and the outside world from the Zimbra box. Can anyone please point me in the right direction on some ideas to troubleshoot/fix this? Thanks!
PS: In my /var/log/zimbra.log I'm seeing the following message repeatedly when I searched it for deferred messages:
May 19 16:23:20 zimbra postfix/smtp: 34A2F90126: to=<email@example.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=26462, delays=26461/0.49/0.05/0.15, dsn=4.5.0, status=deferred (host 127.0.0.1[127.0.0.1] said: 451 4.5.0 Error in processing, id=32120-01, parts_decode_ext FAILED: Unix utility file(1) not available, but is needed at (eval 85) line 113. (in reply to end of DATA command))
Update--- I found a fix for this:
Incoming mail did not get delivered to the users' inbox, instead they ended up in the deferred queue. The error message in /var/log/mail.log was:
451 4.5.0 Error in processing, id=16530-01, parts_decode_ext FAILED: Unix utility file(1) not available, but is needed at (eval 85) line 113. (in reply to end of DATA command))
apt-get install file
and restarting zimbra fixed this.
