Sorry, I don't get it. How did you get the 1000+ contacts onto your phone? You must have done something, they would not pop up out of nowhere. I had to add every single one of my ~60 contacts manually.

EDIT: Oh, and that automatic adding of contacts I send emails to. I do not get that either. I have never used that feature and would never use it so I never even looked for such an option. I looked now and... could not find it. Not in Sailfish anyway. I found it on my N900.
