Hi there I have recently started using Thunderbird again on my iMac and have noticed when I send a email using Gmail the sent email is showing in my sent folder on my Gmail account but is not showing in the sent folder on Thunderbird the only emails in my Thunderbird sent folder are emails I have sent using Thunderbird any emails sent from devices like my iMac or iPad are not showing up in the sent folder on Thunderbird.

I am not sure why this is happening any help would be much appreciated.
