Using the same custom header multiple times (x-mailgun-tags)

Hi, I'm trying to use "x-mailgun-tags" headers two times for my email as Mailgun supports up to 3 tags. However, it seems that only 1 tag out of 2 is registered every time it sends. Does anybody know whether Thunderbird supports using the same headers multiple times? Thank you.

Hi Matt,

I'm using two lines one for each tag like the attached screenshot. I also tried putting them in one line with comma(tag1,tag2) and also with quotation+comma ("tag1,tag2") but both didn't work.

ok lets try that again. How to you get X anything headers in Thunderbird composer?

I went to configure editor and searched for "mail.compose.other.header", and added my x-mailgun-tag header.
