Hello. I'm trying to forward an email to about 20 people from an Outlook address in Thunderbird. The email has 1 MB attachments. After I click send this error comes out : "An error occurred while sending mail. The mail server responded: 5.3.4 552 5.3.4 Header size exceeds fixed maximum size. " I've been googling but couldn't find any solution. I've even tried sending the same email without any attachments and it's still not working. Just yesterday I've been forwarding an email from the same address without any attachments to the same people and it worked well.

Will be grateful for any help!

You can try to create a mailing list. http://kb.mozillazine.org/Thunderbird_:_FAQs_:_Create_Mailing_List

Alternatively try to reduce the number of recipients or talk to your email provider. The error message is from their server.
