Plus Addressing

[Martin Campbell]

Has anyone else tried using plus addressing in Kolab? I mean email
addresses of the form user+***@domain.
It appears that both Postfix and Cyrus IMAP are configured to support
plus addressing by default in Kolab.
Email sent to user+***@domain will be delivered to ***@domain into
subfolder suffix, if it exists, otherwise into INBOX.
I've tested it, without making any configuration changes, and it seems
to work exactly as expected.
Is there anything else I should know about using this feature?
Further documentation on Postfix and Cyrus IMAP support of plus
addressing is here:
