not mail with SQUIDGUARD

[philippe34]

Hello,
I have a little problem with the Squidguard filter, when I activate it I can not connect to my mailbox anymore

 I have 3 mailboxes that I report with the client outlook under android:
 hotmail.fr: (it works)
 gmail.com: (I receive the notification but not the mail in the box and can not send it)
 Exchange: the box of my work (nothing works)

 I tried to activate Squidguard without blacklist in 'all' the filtering is no longer operational (normal since [all]) but still the same problem.

 Proxy squid is set for HTTP and HTTPS / SSL in transparent mode, everything works fine except the mail boxes.

 the filtering that I do with Squidguard is important because I have 2 children who starts to fiddle with the keyboard ...

 if anyone has an idea because I dry.

 Thanks for your help
 cordially
