Email notifications sent by Drupal have broken links sometimes

Question

I'm using the Subscriptions module of Drupal to send out subscribed emails on a regular basis and I've noticed that the links embedded in the email will break if the link is too long, but only for some users. The email client that user is using is Entourage. The crazy thing is that I use Entourage, also, but I don't have that problem with the links in my subscription emails that are sent to me. Here's what's happening:

http:samplelinkhere?var=blahblah
blahblah

The top line of the link will be underlined and part of the link, but the bottom part will not be underlined (even though it should be) and so, the link is broken. Does anyone know how to fix this issue?

AFAIK, there is not much you can do about this. As long as the links do not contain line breaks in the original mails sent by your server, it is up to the receivers mail client to add line breaks for readability, usually based on some user preference settings (Which could explain the difference to your own Entourage client).

Also, some clients try to detect links and avoid breaking them, others don't, and some even have plugins for this.

A possible workaround would be sending HTML mails instead, but that opens a huge different can of worms concerning mail client compatibility, so I do not recommend it.
