Here are my setting which seem to work. I'll use "username" for the part before the @... I happened to use this for the "Account name" field too, but I'm not sure that matters.

Account name: username
Account type: pop3
Name: actual name, or blank I suspect
User name: username@gmail.com
Password: ********
E-mail address: username@gmail.com
Incoming server: pop.gmail.com
Outgoing server: smtp.gmail.com
Use connection-specific SMTP server: unchecked

on Advanced settings:

Incoming:
Retrieve: Messages and attachments
Leave messages on server: checked
Password authentication: normal
Security: SSL(pop3s)
Incoming port: 995

Outgoing:
SMTP authentication: Login
User name: username@gmail.com
Password: *******
Security: SSL
Outgoing port: 465

Security:
Encrypt... : unchecked
Digitally sign ....: unchecked
Display security indications for:
All encrypted...: checked
All untrusted...: checked

Took a lot of trial and error to get this to work. Maybe Nokia can get together with Google to put these specific settings on the Google help page for POP forwarding.

Warning: the e-mail program doesn't do too well when Google has several hundred messages for it to download. It grinds to a halt , and/or crashes. So make sure you set Gmail to only pop NEW messages or you will overload the device. If you get a dozen or two messages at a time you should be OK, but I don't think the N800 will be very good as an e-mail archive with the current software.

Also... you may already know this, but you can't send YOURSELF a message with Gmail.. it just gets ignored. So test this using a separate e-mail address. Also, messages you send on Gmail using the web interface (via the N800 or a PC) will also show up in your inbox on the N800. I think this is nonstandard pop behavior, but it comes in handy at times too.

One other thing... gmail doesn't allow messages that have been poped to the N800 (or anywhere else for that matter) to be erased. I think this is also non-standard pop behavior... but I like it because I have wiped out large e-mail archives in the past due to not getting the client settings right the first time. So I have "Leave messages on server" checked on the N800, but it wouldn't matter anyway unless the Gmail end is set up to allow it (which I don't recommend).

Good Luck!

Thanks, Macbeach,
I just tried your settings on my 770. Still not able to send email and get the SMTP authentication error.

Anyone else have any ideas?

Using Normal(TLS) not SSL
and port 587
works for me.

I also don't use the @gmail.com in my User name.

Got it working! Deleted account and created new one with the same settings I had been using. Now it's ok.

Thanks for all your replies,
Neil
