Is there any way to have gnus put your sent emails in the Sent folder through IMAP?

Hello,

I am trying to switch to gnus for my main email client, however I cannot figure out how to get a copy of each email sent to my default Sent folder used by other email applications that was created by my provider (Posteo to be exact).

I have tried different things, such as by seting archive folder and attempting to gcc, but none of these have worked.

Additionally, I see many posts online are about doing this with an archive about once a month, whereas I just want each individual message to be placed in the "Sent" folder when it is sent.

Thank you.
