My Ubuntu server is configured with this tutorial. http://www.howtoforge.com/virtual-users-and-domains-with-postfix-ubuntu-7.10-p3 Last night, I performed an Code: apt-get update apt-get upgrade It appears that authmysql was upgraded as a result. This morning, it has come to my attention that Courier-IMAP is not working. When I check the listening services using netstat, the only one in the list is courier-pop. The following are all missing: courier-imap, courier-imap-ssl, courier-pop-ssl. If I execute /etc/init.d/ on any of the missing services, I don't get any kind of confirmation that they restart, stop, start, fail, etc. Any ideas on what I can do to get IMAP working again? My users are already complaining that Squirrelmail doesn't work due to the IMAP service not running. Thanks.
