I've attached my script in case it's helpful to anyone in a similar situation. It took quite a bit of effort to get this right, highly depends on the format of the original mailstore, and I've only tested this on one smaller mailbox (<400 messages). And I wasn't concerned with any client having to download everything again since this was a fresh import.
In any case, it worked for me.
Err had a few issues on a larger 4gb mailbox:
small bug in the script, new script attached. Change: # Grab the flags from the filename. F=
echo $fname | cut -c 26-27to: # Grab the flags from the filename. F=0xecho $fname | cut -c 26-27without the 0x in front, the masking operation interprets $F as octal.
there are cases where the old mail server wrote files with identical timestamps even though the dates of the email are clearly different. I presume this was just buggy behaviour and could explain why I couldn't successfully download via imap.

I may consider fixing this.
- for some reason there were some off by one file sizes that resulted in errors like this: dovecot.index.cache: UID 278: Broken physical size in mailbox ... failed: Cached message size smaller than expected (1972 < 1973 ,box=INBOX, UID=278)
In my case 298 out of 22023 files were affected. Script to fix this is
after using the import-from-icewarp-files.sh script is attached. I
couldn't find a good way to find only maildir messages by filename.
Seems difficult to parse. When I renamed the files, I used icewarp as
the server name and that's how I searched for files:
FILES=find /path/to/mail/user -name \*\.icewarp\,\*
If there's a better way to do this, I would like to know for future reference.
Thanks, Stef
