Fresh install of ispconfig 3 on centos 5.5, i followed the 64bit perfect server, but the machine is actually 32 bit. I installed ispconfig, but dovecot was screwed up cause it didnt install properly. I have since removed the old dovecot and added... rpm -ivh http://wolfcastle.wu-wien.ac.at/dist/rhel5-i386/RPMS.at-testing/dovecot-1.2.13-1_111.el5.i386.rpm rpm -ivh http://wolfcastle.wu-wien.ac.at/dist/rhel5-i386/RPMS.at-testing/dovecot-sieve-0.1.17-5.el5.i386.rpm and restarted dovecot [root@server32 tmp]# telnet localhost 143 Trying 127.0.0.1...

Also their maildir exists ok and seems to have a few autogenerated files in. Run out of ideas to debug now, can anybody help?
