Hi, I recently switched hmail's db from MSSqlCE to MySql. I had to re-create the domain and accounts in hMail, (there was only 3 accounts ). Now I can't send mail from RC, err:535, but I can login. I can also send mail from thunderbird authenticating with hMail's SMTP. The POP works fine in RC too. Does anyone know why the IMAP authenticates from RC but the SMTP won't anymore? Should I delete the RC db and re-create it? Is there a password hash that was saved from the previous MS database or something because the accounts are identical but they now use a different hMail db? Any help would be great.
