IMAP emails sync example from Yandex to Titan email service

IMAPsync.sh

# This example shows how to transfer emails from Yandex to Titan using the following:
# - proper use of SINCE and BEFORE keywords to select only some emails
# - proper hosts, ports and SSL configuration
# - skip of empty folders (empty folders are not created on destination)
# - email reports are not saved
# - no folder size calculation (it takes too long for big mailboxes with size of 10 Gb+)
# - correct matching of Yandex folders that have Russian names such as "Отправленные", "Отправленные_0", "Удаленные", etc,
# - skip other folders like "Junk Emails", "Infected Items" or "Исходящие" folder because it's "Outbox" that is missing on Titan.
