Is there a common port I can block that will prevent users from downloading email from webmail services such as aol,hotmail or msn, usedby all - without blocking www service in general?Try port 110 (pop3), 995 (pop3-ssl) and maybe 220 (imap3) and 993 (imap3-ssl), too.
That won't help - he's talking about Web-based services, and those go through port 80/443. The only chance is to block file downloads on the proxy-server - and even that won't work if the Webmail service offers SSL. -- Mit freundlichen Gru?en / Yours sincerely Juergen Nieveler Akzo Nobel Deco GmbH IT / Netzwerk & Systeme eMail: Juergen.Nieveler () AkzoNobelDeco de Disclaimer: Views are mine, not my employers' -- -------------> IMPORTANT <---------------- This message, including attachments, is confidential and may be privileged.
