Setting up my email accounts in the N900 Mail Client has been very frustrating. I have a simple Prepaid-telephone only SIM card, so I use my home (or free WiFi outside) WiFi for Skype & internet (which works great!).

I have tried to set up my Gmail, my Ovi.com and my Yahoo accounts. At the moment they all seem to work partly. For the Yahoo account I first changed to Yahoo! Asia to make it work on IMAP/POP (as mentioned in an other thread). Now I am in fact able to receive my mail on all 3 accounts, and in fact the N900 Yahoo account receives mail much faster (a few minutes!) than my regular laptop.

However, I am not able to send any mail from my Gmail or Yahoo, and get the message "Unable to connect to SMTP server smtp.mail.yahoo.com".
What do I do wrong? Why can I send mail with Ovi and not with Yahoo or Gmail??
