Hi

I have been using KDE's Kmail (under Kontact) for a long time. I want to migrate to Opera with all my bags and food --- under Opera's email import I do not see the option of importing from Kmail or similar. How do people do it if they do?

Regards,

Yes there's not something to import the settings all at once.
You have to manually recreate your servers account.
You can then copy the mail boxes using an IMAP server as an intermediary, or exporting kmail's inbox as UNIX mboxes, and then importing them from Opera.
I don't see any options to have opera import the addressbook from other sources than opera - you can use this online service:

I know all of this is a bit too tricky!

So I managed to transfer my mail from Kmail to Opera. Thanks to a suggestion from GeekPhreek.
* go to a mail directory in kmail
* select all mail in above directory
* saves as some .mbox file in your system
* in the event of multiple folders (like me), repeat above for each folder, hence you would in the end have multiple separate .mbox files
* launch Opera and do a File >> Import and Export >> Import Mail >> Import generic mbox file
* at that stage select your account and hit "Add mbox"
* a dialogue box will appear, select the .mbox files created earlier and hit "Open", and then hit "Next"
* thats it --- now you should see your directories in Opera under "Filters"

Two things I did not enjoy in the end:
* Unfortunately, this filters also have the same names with the .mbox extension --- I renamed each filter by removing the suffix. So thats cool.
* I see all the mail in these various filters also appear under "Received" --- so I have a long list of all the mail under RECEIVED tab. I wish I could only see the current messages in that tab, assuming it is equivalent to some INBOX directory that I am used to in Kmail. Oops ... I should not compare the two clients they are different, thats why I migrate to Opera in the first place.

I think I will enjoy Opera --- I like its multiple functions.
