I received this email from DH yesterday:
[i]We're making some changes to our email policy starting January 5, 2015 in order to improve email performance.
Large mailboxes can cause serious performance degradation for not only our servers, but also for email clients. In order to help keep everything running smoothly, we will be automating the deletion of mail in Spam, Trash, Junk and Deleted Mail folders that are older than 30 days.
The initial batch of deletions will occur on January 5, 2015. From that point forward, any email in your Trash and Spam folders will be deleted based on the age of the messages.
Please take some time to ensure that you, as well as any users of mailboxes under your domains, are not storing important messages in these folders. If you need to archive messages, create another directory for these messages.
If you have any questions regarding this policy, please don't hesitate to contact us!

In my business, I often refer back to deleted messages (currently in Trash folder) for information about previous orders. Permanent removal of these messages would be a huge problem.
I'm set up with IMAP, would changing the name in T-Bird from "Trash" to something else prevent DH from removing messages in the folder? If not, are there any suggestions for preserving deleted messages?
