Hello, My system: FC4, kernel: 2.6.12-1.1447_FC4, selinux targeted, enforced, installed: selinux-policy-targeted-1.25.4-10.1, selinux-policy-targeted-sources-1.25.4-10.1 squirrelmail-1.4.4-2 If I setenforce 0, then users can log in squirrelmail and read/send emails w/o problems. If I setenforce 1, then users cannot login sm. The error message is: Error connecting to IMAP server: localhost. 13 : Permission denied However, the system log does not show error message about it. So, if I run the selinux command, I got: # audit2allow -l -i /var/log/messages -o /etc/selinux/targeted/src/policy/domains/program/apache.te # make load make: Nothing to be done for `load'. BTW, users can still run pine to read/send emails. I tried to set squirrelmail's server setting using sendmail or smtp, but no help. Can somebody tell how to solve the problem? Thanks! Hongwei Li
