New csf v7.00

Changes:

• New feature SMTPAUTH_RESTRICT – This option will only allow SMTP AUTH to be advertised to the IP addresses listed in /etc/csf/csf.smtpauth on EXIM mail servers. The additional option CC_ALLOW_SMTPAUTH can be used with this option to additionally restrict access to specific countries. See csf.conf and readme.txt for more information
• New FASTSTART procedures in csf and lfd to centralise functions and add error reporting
• FASTSTART added to GLOBAL_ALLOW, GLOBAL_DENY, GLOBAL_DYNDNS, csf.deny, csf.allow, Port Settings, PACKET_FILTER, DROP_NOLOG, SMTP Block, DNS
• Remove duplicate IP addresses from individual blocklists
• Remove duplicate IP addresses (not CIDRs) across blocklists as they are newly retrieved
• Ensure /usr/local/bandmin/bandminstart exists and is executable on cPanel servers before using it
• Removed MySQL version check as it is currently redundant from Server Report
• Improve Net::CIDR::Lite use integrity to prevent unnecessary lfd failures
• Ensure GeoIPCountryWhois.csv is removed before processing a new d/b download
• Add /etc/csf/csf.smtpauth to UI if SMTPAUTH_RESTRICT is enabled
• Fixed issue with IPv6 generation of SMTP_ALLOWUSER rules
