Hello,
This is my first post to this group. I have read through the instructions
before posting. I hope am doing the right thing. If not my sincere
apologies.
I am in the process of developing a dovecot IMAP plugin (over v2.2.25). The
plugin works with mdbox/sdbox which has ability to keep attachments as
external references (via SiS POSIX). The plugin must enable fetching
attachment from REDIS instead of local-store.
To accomplish this I was following dovecot via my debugger. I wanted to
understand if there was a way to determine a message_part to be of an
attachment type ?
Thanks.
