sdbox begins with a small dbox header, followed by the message text and finally a dbox metadata footer. Something like: 2 M1e C4e327f7d ^A^BN 0000000000000906 <message text here> ^A^C R4e327f7d V94e G39670b147d7f324e0e1d000074ccac23 dbox-file.h describes the headers and lists the metadata characters and what they mean. Because of this extra metadata I don't really know if it would be a good idea to name them *.eml. Yes, you could copy specific sdbox files elsewhere and run "doveadm force-resync" on them. All message flags would be lost though, since they're stored only in Dovecot's index files.
