At office, the owner requested me to put web-filters to block facebook, youtube, orkut etc. ok, so i put in a proxy server (actually i tried 3 -- ccproxy, analog proxyi and winproxy). everything worked just as requested until outgoing mails.
The mail service provider is using port 26 for smtp instead of 25 which is giving me a good sort of trouble. the mail client (windows mail, outlook and outlook express) keeps asking login information every time a mail is sent. it seems not to accept anything, and mails dont go. the proxy servers allowed me to change smtp port to 26, though.
Is there a way to put in web-filters without using a proxy server, and if not, can the proxy be bypassed/configured for smtp port 26 by the mail clients?
for the time-being, i've suspended to proxy servers.
thanks in advance.
