SMTP RFC5321 specifies limits on maximum length of message line.
Sendmail breaks long lines to avoid crossing the limit.

FIXES to choose from:
1 . You seem to send html context. You may use tidy program to reformat your html. It should also break long html lines.
2. You can send using quoted-printable enconding. It encodes non ASCII characters and takes care of line lengths.
