WebMail Lite 8 supports message threading. The feature is also known as conversations, it presents a handy way of organizing messages on the same matter into threads.
When you send a message in response to some other message, email client will save the information about that original message in this new one you send. And when the conversation continues, it will be possible to track it from the first to the last message.
Note that enabling threads increases load on the server.
If you experience performance issues, or any additional load is unwanted, disable threading
How threading works
WebMail Lite 8 will properly handle threading information when sending responses out, and will show threads in a message list:
Take a look at a message at the top of message list, it contains a mark stating 2, which means the thread contains 2 more mails. Click that mark to open the thread:
If thread contains more than 6 messages, the thread will be opened in chunks, and you'll need to click "More messages" to get next 5 mails.
How to enable or disable threading
By default, threading is enabled, you can disable it in admin interface for specific mail server:
Assuming admin has the feature enabled, users can enable or disable mail threading in account settings:
How to check if threading is supported by server
It's required to make sure IMAP server you use offers support for threading. The most straightforward way to check that is using telnet. Run the following command, with your IMAP server hostname supplied:
telnet imap.domain.com 143
Once connected to server, log into your IMAP account:
a login firstname.lastname@example.org yourpassword
After logging in, you'll get a list of supported IMAP capabilities, something like:
a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY

To determine whether threads are supported, we're looking for:
Message threading will be available if any of the above capabilities are available on IMAP server you use.
