What the hell are these arbitrary nsmail-#.tmp attachments and how do I stop them so my mail isn't rejected via rule-happy servers?

My mail is getting arbitrarily rejected by Amazon e-mail servers due to, apparently, attachments created by Thunderbird behind the scenes. Many of these were sent with no attachments added, which only adds to the confusion.

Here is a sample blowback message:

Unfortunately, I was unable to deliver your mail. The error given was:

AmazonSESException: Status Code: 400, AWS Service: SES, AWS Request ID: 9e25a0b3-540e-11e6-b7f0-c7219b1a344e, AWS Error Code: InvalidParameterValue, AWS Error Message: Illegal filename 'nsmail-5.tmp'.

Zenos,

Thank you for your response but I don't think it applies. I send normal e-mails and somehow Thunderbird is creating temporary files and attaching them to the mail before sending. They have the form nsmail-#.tmp (for instance nsmail-1.tmp, nsmail-2.tmp, etc). While an attachment does not show up in my sent items or outbox, one arrives at the mail server.

Further, I wasn't archiving and didn't see any messages about archiving the last few times this has happened. This may only be happening when the mail format is HTML.

Thanks again.
