Backing up an entire mailbox every time seems unnecessary when I only need emails from specific dates or projects. I am looking for a solution that can narrow down the messages by sender, recipient, subject, or date range without making the process complicated.

I found the DRS Softech IMAP Backup Tool , which includes date-based and advanced mail filters for fields such as To, From, CC, BCC, Subject, and Body. It also supports duplicate removal based on email attributes and an incremental option that skips previously migrated messages. Another useful detail is that attachments can be saved separately with a custom folder name.

The software also has a preview option for checking folders and email counts before exporting. Has anyone tested these features on a mailbox containing years of emails? I would appreciate recommendations for creating selective backups while keeping everything organized.
