I would like to access email behind a corporate firewall; however, the only options for Treo Mail are Visto Mail Server (my company won't do this) and leaving my office machine on and connected to network/internet (not usually possible). In addition, I don't want to/can't download a lot of company emails to the Treo anyway due to security/confidentiality concerns. However, I can access corporate webmail if I dial into the company's intranet (from my laptop); however, this defeats the purpose as I could then just download it to Outlook on my laptop anyway. My idea is to use the Treo to dial in to my company intranet and log in. Is this possible? I read somewhere, though, that Blazer could probably not access corporate intranets behind firewalls. So this doesn't look like a possibility. Any comments or potential solutions?

Thanks!
