replies being sent to receipients replies

[Kimmy P]

i have had a few of my contacts receive blank emails from me when they reply
to the email i sent to them. also this reply does not show in my sent folder.
it seems it's an automated reply from my address but i don't have anything
marked for requesting such a thing

I am having the exact same problem as Kimmy. Some of my contacts receive
blank e-mail replies when they write to me. I have no rules for auto
response set up. What is causing this?
