Large POP inbox timing out

I have a large inbox, Pop3MailboxInfo MessageCount says 10596, so connection is good.
I build a query for emails from last 5 days only
Dim builder As MailQueryBuilder = New MailQueryBuilder()
builder.InternalDate.Since(dateSince, DateComparisonType.ByDateTime)
Dim query As MailQuery = builder.GetQuery()
however, both attempts below timeout
Dim messages As Pop3MessageInfoCollection = client.ListMessages(query)
or
Dim asyncResult As IAsyncResult = client.BeginListMessages(query)

any ideas?thanks
