yes that is the part we have also seen in your eml. it actually does not contain html, but is already converted from rtf to html. But unfortunately neither with your eml nor when hooking up Outlook via imap and setting the format to rtf we could observe a crash of the dagent.
I’ve done the import on a new created store (also user was recreated before).
The version of the migration tool I have used for this is 22.214.171.1242 (from the last nightly build)
yes the path changed for the binary (but it did so in the later 7.2 releases as well). Generally speaking I would very much recommend to switch to lmtp delivery instead of delivery via pipe (config is explained in the manual).
