Save copy of sent message only in a specific account

I use EM Client with two IMAP accounts.  I just wanna save copy of sent messagens in one of them.   Is it possible?  When I check the option “save copy of sent messagens in ‘Sent’ folder”  this causes a copy message on both accounts .

Unfortunately, the option you mention is a global option, that is it applies to all accounts. A workaround might be to turn this option off and create a rule for the account you wish to save the sent items for. The rule can be created to copy the message to the sent folder after sending. Have not tried this, but should work.

Thanks a lot for this workaround , Jay! Works great!
