stevef, I think the problem is that GMail uses POP3 over SSL, which as far as I know, on RISC OS, only NetFetch/Hermes can do. Even then, I don't really like the idea of having duplicates of all my mails stored locally on my RISC OS machine, I'd rather keep the whole lot on GMail, so I can access them anywhere, and the searching is very good too. Really, what I'd like to see is a GMail backend to MPro4/5 in the same way they have POP and IMAP backends.
Even then, MPro4 is still lacking for me, as it only handles one IMAP account at time, so you have to switch between your accounts to check for mail, compared to Apple Mail or Thunderbird, which support many IMAP accounts all at the same time.
If MPro6 appears with GMail support, and support for many IMAP accounts, then I'll upgrade from my MPro4.
