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.
[solved] No, there was nothing in the logs. I did figure out what the problem was though and how to fix it. I browsed to the /etc/init.d/ folder and then typed ls -l. I noticed that of all the files in that directory, the three services that were giving me problems all had a file size of zero bytes. I opened each of them up and confirmed that they were empty. I can only believe that something during the apt-get upgrade caused them to be overwritten with empty files. For each service that wasn't working (courier-imap, courier-imap-ssl, and courier-pop-ssl) I typed apt-get remove --purge [service name] and then did a reinstall. I then checked that the file in /etc/init.d/ was no longer empty, which they weren't. I performed a restart of each service and did some testing on the IMAP server and everything worked as intended. I posted it all here just in case someone runs across the same problem down the road. Thanks.
