Hi, I hope someone have the answer.

Before, if I send an email to the name of an e-mail list (e.g. friends3)
and write in to: field friends3, thunderbird understands that's an email
list and change this address with all emails into this list.

What is happening now: I have an email list with this data:
List name 3Solar
List alias 3so...@myname.com.br

adresses do insert in the e-mail
adre...@something.com.br
adre...@something.com.br

(like it always was)

Now, when I send this email I get this message:

There was an error by sending your message. The e-mail server returns:
5.1.3 The recipient address <3Solar> is not a valid RFC-5321 address.
Please check the recipient from the message "3Solar" and try again.

What must I do?

Thank you
regards
w

Try hitting the Tab key instead of the Enter key to enter the list
address. This step is necessary now when using MailMerge, so it might
also work with lists.

I've seen this reported twice, both times caused by the sigswitch addon.

But I'm sceptical that it's the only or prime cause.

Does it work if you delete the alias or nickname?
