= sign at end of plain text sent by mailer

Rails v2.3.8; Ruby v1.8.7
When sending a plain text email using ActionMailer, the email contains
= signs at the end of long lines.

This is a problem as I'm including a link which is bound to break over
more than one line and so the user will not be able to cut and past it
into a browser.

Can anybody tell me how to stop this behaviour please?

Thanks

Do you see the = when you view the email? I believe most clients handle it, strip it out, and merge the two lines...

I was looking at the emails using MockSMTP; sending them to a 'proper'
email client suggests that you are correct.
That'll teach me!

Thanks for replying.
