[Dovecot] can i set "folder alias"?

when i use mailclientA to send mail, then the mailclientA program default will save it to folder "sendA", when i use mailclientB to send mail, then the mailclientB program default will save it to folder "sendB".

i know i can configure the mailclient program to use which folder, but can i set something like "folder alias"? imap { # ln -s sendA sendB folder alias = "sendA = sendB"; folser alias = "draftA = draftB"; ....... }

i use dovecot-1.0rc17, imap, maildir sorry, i don't speak english
