Hello RudTor, There is different way to access gmail. 1. Through a web-browser. 2. Through imap, smtp, pop3 mail client ( Example-microsoft outlook) To access through browser, only ssl ( for https://gmail.com --- port 443) and web-browsing ( http://gmail.com----port 80) will be enough as a dependent application. Need not to allow all dependent applications unless you are using it. Explain your customer, if he only wants to access gmail through a browser, then he can allow SSL and web-browsing application along with gmail-base. He can safely ignore the dependency warning for smtp, pop3 and imap. Here is an example, while i am accessing https://gmail.com through a browser. Hope this helps. Thanks
