ok/i fixed the problem .i set aqua and the mailclient to imap.does someone knows if i will set the two to pop will i be able to sync both sent folders so anything sent from one will be seen in the other?
Pop was not designed to maintain sync between folders in that way. It is in a sense only half a standard, as it only deals with collection of incoming emails from the server. When incoming mail uses pop, outgoing uses smtp, and sent copies are only kept locally, so sent messages are on your phone or your pc, but never both. Not very convenient.
Use Imap on both devices, as it allows the different devices both to synch to the server.
You may worry that not all incoming messages are kept on the local device, and so there is maybe a performance hit when searching or fetching new emails, but really it is a tradeoff between speed, memory used and other elements of performance (such as data used on your data plan). Provided you don't allow the server to delete old messages, they are all still there, until you choose to delete them. obviously watch your quota! I have configured my pc to download all the messages in full and keep them forever. This allows me to do local backups on the pc.
One important thing, if you use IMAP, and "delete" a message, that deletes it everywhere!
Aqua mail can hide older messages but that is not the same.
My tablet uses something close to the default settings that come with aqua mail, so does not keep them all on the tablet "live".
There is plenty of good stuff on the internet about how IMAP operates. I don't know how well this corresponds to how google drive, gmail, and such providers actually operate. I run a server on my Linux based hosting account, so it is pretty standard.
