Is this a natural english writing? (For this problem, I won't put more effort...)

[Lee12jan]

Dears:

I wanna express that I won't spend any time, any effort to solve one
technical issue. so I write:

==========================================
For this problem, I won't put more effort into solving it ?
==========================================

Is it a natural eng writing ? thanks.

Hi,

I would start with 'I want to express ....'

I would write as follows:

I won't put any more effort into solving this particular problem.

Dear Alan, thanks for your advice. I'll keep it in mind.

Good morning Alan,

How do you feel about using "Dears" as a greeting line? Maybe it's just my untrained German ears that think something is missing here. For example, 'my dears' sounds much better to me. What about you?

Thanks,
