So, I hope I understand you correctly
I have wirtten a Script which update the Userpassword and the IMAP-Password from the Users if they change her password, because it doesn't work before. If I change my password now also only numbers I get this message but he change the IMAP PAssword corretly.
I can use this password for login because i have wirtten this script which change the imap an userpassword.
Sorry for my veryvery bad english
