In my n900 I have configured an IMAP email account for my provider email. This used to work fine until 2 days ago. It does not sync with inbox anymore.
I think it is DNS related because ever since this email stopped working, also my connection to the repos stopped working when i selected download. I received DNS errors, but when opening the same domains in the browser there was no problem. After doing an update in stead download I can also contact the repos again for downloading.
Also when i use the same imap settings on my PC it works fine..

Questions:
- Now I have to guess that the problems are DNS related because the email client does not give any error messages. Where can I find a logfile for the e-mail client.
- Is it true that software like email and application manager use different network (DNS) config settings? Where can I find those settings?
- In general: how to flush DNS cache(s) in N900?
