It always asks my password for id-file when it tries to check for Emails.

This is Lotus Client security built-in solution, and it's possible to disable it (it decreases safety):

It's somewhere like (have Polish Lotus client): menu File → Protection (or Security) → User protection → Basic security data (first tab) → "Don't ask for password in other Lotus Notes applications". If I find some other solution on Lotus API it will be updated. (And I found, see step 3 of installation instructions above).
