I blanked a bunch of mail files for mailing lists that I'm on with:
for f in *; do
        echo > "$f"
done

Now mail crashes when I enter those folders.

2. Remove all .sbf files.
3. Access the mail file from within Mozilla/Mail.


Actual Results:  
Everything closes.

It should have rebuilt summary files and then worked normally.

so these are local mailboxes with 0 size?

Comment 2

[R.K.Aa.]

"echo > testing.txt" creates a file size 1 byte, only containing a newline (\n)

Comment 3

[James Lockie]

Yes, 1 byte, newline only.
I have filters that send mail to some of them and those ones work after a
message is filtered to them.
