Just an update. Seems the reboot didn't actual do anything. The boot-up log specified that amavisd started up ok, but when I entered the following in shell
it still return the same error
amavisd dead but subsys locked
I can find the .pid file but not the .lock file. Deleted the .pid file and tried restarting amavisd, but same thing.
Anyway, since I am at the datacentre, I decided to try to do a fresh install on the server and try again. Hopefully, this time it will installed without any problem.
One last question, though I know its out of topic. Assuming that I get this to work, eg. "Virtual Users And Domains With Postfix, Courier And MySQL (Fedora Core 5)", is there anyway to make it work with IspConfig?
Would appreciate any tips, guides or hints from anyone who managed to get this setup working with IspConfig.
