from flask_mail import Message from openbps import mail

msg = Message('Тест длинногоочен письма', html='1231231 3123123', recipients=['[email protected]'])

mail.send(msg)

and get email with subject "Тестдлинногооченписьма"

Subject: =?utf-8?b?0KLQtdGB0YI=?= =?utf-8?b?0LTQu9C4?= =?utf-8?b?0L3QvdC+0LM=?= =?utf-8?b?0L7QvtGH0LXQvQ==?= =?utf-8?b?0L/QuNGB0YzQvNCw?=

if send short subject, get "ok" if set charset as cp1251 (for example), get "ok"

but need long subjects with utf-8

I have the same problem too with cyrillic subject

I solved it by changing default MAXLINELEN value in email.header module. Seems like nonascii header splits by MAXLINELEN parts when encoding, and it somehow reflecting on spaces between words.

I've just put the next code beside my flask-mail app initialization:

from email import header
header.MAXLINELEN = 32
