I suggest you drop SG entirely and move that config into your squid.conf: # Time rules # abbrev for weekdays: # s = sun, m = mon, t =tue, w = wed, h = thu, f = fri, a = sat acl non-working-hours time MTWHF 18:00-24:00 00:00-08:00 acl non-working-hours time MTWHF 18:00-24:00 00:00-08:00 acl non-working-hours time SA 00:00-24:00 # Source addresses acl exempt src 10.0.0.90 10.0.0.167 acl youtubers src 10.0.0.1-10.0.0.4 acl localnet src 10.0.0.0/24 # Destination classes acl blah_domains dstdomain "adv/domains" acl blah_domains dstdomain "deny/domains" acl blah_domains dstdomain "porn/domains" acl blah_domains dstdomain "spyware/domains" acl blah_domains dstdomain "socialnet/domains" acl blah_urls dstdom_regex "adv/urls" acl blah_urls dstdom_regex "deny/urls" acl blah_urls dstdom_regex "porn/urls" acl blah_urls dstdom_regex "spyware/urls" acl blah_urls dstdom_regex "socialnet/urls" acl stuff_always_blocked anyof blah_domains blah_urls acl whitelist_domains dstdomain "whitelist/domains" acl whitelist_urls dstdom_regex "whitelist/urls" acl whitelist anyof whitelist_domains whitelist_urls deny_info 302:http://example.com/squid/denegado.html whitelist acl youtubers_domains dstdomain "socialnet/domains" acl youtubers_urls dstdom_regex "adv/urls" acl youtubers anyof youtubers_domains youtubers_urls deny_info 302:http://example.com/squid/denegado.html youtubers # Policies http_access deny !localnet deny_info 302:http://example.com/squid/denegado.html localnet http_access allow exempt http_access allow youtubers !stuff_always_blocked http_access deny youtubers http_access allow non-working-hours http_access allow whitelist !stuff_always_blocked http_access deny whitelist http_access allow localnet deny_info 302:http://example.com/squid/denegado.html all http_access deny all > >> >>> squid.conf: http://pastebin.com/TQ8H6bRp >> >> Quote from your config: >> >> acl Safe_ports port 587 #SMTP >> >> Did you read Amos' reply "SMTP is the #1 worst protocol to let anywhere near >> an HTTP proxy.

Bogus. You should know it is possible that two pieces of software can run on one machine without interferring with each other. Whether or not a mailserver exists on the same machine has nothing to do with Squid. Your mailserver itself should be using that port and controlling what traffic can use it. *HTTP* traffic should never be allowed to flow from the proxy software through to the mailserver software.
