can't send group emails
when I send serveral emails in one batch it fails and this message comes up: Get a message “An (SMTP) error occurred while sending mail. The server responded: Server busy. Please try again later (#4.3.1).” I can still send single emails wth the same account and server

Has this ever worked for you?
It would seem that the SMTP server might be configured to work with a somewhat small number of addresses per message; this could be a klunky and lame anti-spammer precaution on the part of your email povider.
An alternative might be to try a mail merge, where you generate one separate message for each addressee, but if your SMTP is getting choked up on multiple addresses per message, firing a lot of messages at it in short order would probably have a similar effect. :-(

The bulk send-out was working one day before. My server provider checked on their side - its OK, so it is something in Thunderbird
Well, it's a message from a server. That's not to deny that something has changed in Thunderbird to provoke this, but so far you're the first user to have reported this issue.
Just to be clear; is a "batch" just a lot of separate messages in succession, or is it triggered by using a mailing list, or a few messages with large numbers of addressees?

Same email with a large number of addresses. Another problem was when adding, say 300, address to the BCC it causes Thundrbird to crash. Perhaps this helps to identify the problem?
re: I send serveral emails in one batch
Are you sending this using a created thunderbird 'Mailing list' or using addon 'Mail Merge' or just selecting several contacts?
Some servers set a limit on the number of emails you can send in a 'batch'. Other servers set a limit in the number of emails you can send in a given amount of time. What is ISP and server?
