Hello,
i have a problem about installing secure_login plugin for squirrel mail . after installing secure_login i can not view login page.
my server :
centos6.2 , postfix , SSL/TLS , dovecot , httpd + php5 , spamassassin + clamav .

Best Regards,

Would you please clarify by what you mean by "installing secure_login"? Normally when you say secure login for Squirrelmail, I think of using an HTTPS page instead of an HTTP page, possibly with a redirect to catch inadvertently typing in http. Are you having problems establishing an HTTPS page or something else? Squirrelmail will also support TLS, which still uses PLAIN SASL login over the standard ports which gets confusing because there are multiple standards (mail over SSL on secure ports as well as POPS and IMAPS, STARTTLS, etc).
