How to stop saving SENT messages on Gmail server?

[tkt2786]

Hi,
Every message I send from Gmail on my phone (HTC One S) shows up twice when I log into Gmail from an Internet Browser. I read this:
https://support.google.com/mail/answer/78892
which explains that I need to set my SENT messages to not be saved on the server (so that it shows up only in the IMAP/SENT folder, and not that folder plus the GMAIL/SENT folder).

But I don't see any settings in the mail app to do that. I even looked in the Gmail app, and didn't see them either. Does anyone have suggestions? I am using IMAP and the default mail app on the HTC. I'm also new to smartphones so maybe I am missing something obvious?

Thanks very much.

ETA: Never mind. I switched to the Gmail app and though the settings don't exist to save (or not) on the server, when I send from this app I don't get duplicate sent emails.

I was going to say that if you use the Gmail app, you won't have an issue. It's much better integrated with gmail than using IMAP with another mail program.
