Here is the process to have e-mail addresses setup in Qaurk PDF's.
1. Window -> Hyperlinks. Create a new hyperlink (with any name), set it to "Type= URL" and enter "URL= mailto:e-mail@example.com".
2. Select the text you want to link and apply the hyperlink created above.
3. Export as PDF.
I have not seen people using e-mail addresses that break at the end of line, why would you do that?
You said that the characters and links are corrupted, could you please mention what changed aftr export?
