I noticed drupal includes line breaks in emails it outputs.
For example in
admin/config/people/accounts we can customize message users receive when they signup and/or when they forget their passwords etc..
The thing is, when the emails are sent to the users, they contain line breaks that seem to be completely random and arbitrary.
I first thought the problem came from the webmail provider, so i tried with different services (gmail, hotmail, yahoo etc.. )
Any suggestions on how to fix this ?
