Hello, How common is for the client app to work with SMTPS proxies? I have a vBulletin forum in a backend that I want it to send e-mails to the users through a SMTP server in a different server. vBulletin app works fin with SMTP servers through TLS and SSL but have not tried with Squid yet. I've been told that this solution could be done with an VPN like OpenVPN but since we already have Squid in the frontend as a reverse proxy for the website and in that frontend is also located the SMTP server maybe we can just use the already running Squid. What do you think? Another question: What do I need to use to tell Squid where is the backend? For the reverse proxy I use cache_peer. Do I just need to add this? Or what? acl yes_to_the_25 url_regex myserver.com acl pt25 port 25 http_access allow si_al_25 pto25 Shouldn't Squid run on 25 and the SMTP server on another port like I do with the HTTP reverse proxy?
