Thank you Falko, but i mean that the soap error is that remains, not the intl warning. That was solved unistalling php-intl extension via YAST, clean and fast.
I have lost so much time with this and im guessing this is caused by a php bug (openSuse currentrly suppports 5.3.5 and the php team have the 5.3.8 stable), but who knows...
Im going to migrate accounts via sql, tested it and works fine, also imap login create mail folders fine.
Anyways, thanks for the help!
