I have 3 different mail accounts. Each of them needs their own smtp server. If I send an email with account A with smtp server of account B and vice versa, I get errors from the server, that it won't accept mails from account A but only from its own account B... It would be great if each account had its own smtp server settings
They do. Go to Edit > Mail & Newsgroups Account Settings. To set up additional SMTP servers, select 'Outgoing Server (SMTP)' and hit the 'Advanced...' button. To specify the SMTP server that an account should use, select the account you want in the left-hand pane and press the 'Adavcned...' button. Easy when you know how. :-) Zak McKracken (is that your real name?), does that solve your problem?
User Error -> worksforme
Ok, my fault BUT: I have one smtp server as default. when i try to send my unsent messages this default setting pops up and asks me for my password. If confirm my password, the window will pop up again and again. It also seems to me, that the other account don't always sent with their associated servers, but try to use the default one from time to time
Verified Worksforme. Other bugs exist regarding issues mentioned in comment# 3.
