I got an email using imap in mailspring. Let’s call it test@example.com. My mail provider is modern, so they support email tags. This means if I send an email to test+tag@example.com it will be delivered to test@example.com. This works fine, but if I try to answer the mail it will answer to the wrong mail.
For example: I send a mail from abc@gmail.com to test+tag@example.com. If I click on the “answer” button it should answer to abc@gmail.com, but for me it answers to test+tag@example.com (to myself).
