OK, I see what is happening. If you have spaces in your tags line your email client is creating multiple lines behind the scenes.
For example if I send an email with:
tags: one, two, three, four, five, six, seven, eight, nine, ten, one, two, three, four, five, six, seven, eight, nine, ten,one, two, three
By the time Postie gets it it looks like:
tags: one, two, three, four, five, six, seven, eight, nine, ten, one,
two, three, four, five, six, seven, eight, nine, ten,one, two, three
Note that it is now 2 lines, not 1. This is for historical reasons and tends to break plain text into lines of 78 characters or less.
However, if I send an email with (Note the lack of spaces):
tags: one,two,three,four,five,six,seven,eight,nine,ten,one,two,three,four,five,six,seven,eight,nine,ten,one,two,three
No line breaks are inserted by the mail client.
HTML works because there is another layer of formatting on top of the raw text and the extra line breaks are ignored.

Please send a sample message to [email protected] there shouldn’t be any issue with HTML messages.
