[Dovecot] can i set "folder alias"?

[John Wong]

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
