How can I delete mail from the Gmail server through Mail.app?

I have been using a Gmail account for quite a while now (although I don't get many emails). I have been using Mail.app for convenience but when I went into the mailbox through the actual Gmail site, I noticed that all my messages were still there, even though I had deleted them in Mail.app. How can I fix this while still using Mail.app?

Mail.app is the Apple e-mail client?





Fairly simple. You have 2 ways of doing this.





Go into GMail settings. Under the forwarding with POP/IMAP tab.





You can use either POP download (enable it), and by the second option "When messages are accessed with POP" just select "delete GMail's copy"





Otherwise, enable IMAP, which has 2 way communication between your client and GMail, meaning that any action you perform on your client is duplicated on GMail ... this should apply to deleting e-mails as well.





GMail recommends you use IMAP, but its up to personal choice I think. You can just follow the instructions in the setting screen to set up your client for whichever service you use.





Hope that helps :)
