This is a hobby for me. I have a back up, but with my skills it would take me a long time to restore so I am a bit worried and your guidance is appreciated. I am running Cent OS 4.3 with Cyrus 2.2.12 configured as suggested here: http://www.delouw.ch/linux/Postfix-Cyrus-Web-cyradm-HOWTO/html/ except I have added the following to my imapd.conf: unixhierarchysep: yes duplicate_db: skiplist tlscache_db: skiplist I would like to upgrade to Simon's RPM. Is it safe to download his rpm and run "yum update cyrus-imapd-2.3.3-6.src.rpm"? Also, is there a repo that has stable Simon's rpms so I can automatically stay updated with his rpms that have shown reasonable stability. ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
