I want to write email in plain text. Sometimes I want to include URLs and I don’t want those URLs to get broken by hard line wraps. I’m using Microsoft Outlook 2003 as my email client and my company uses Microsoft Exchange Server (2003 I think). In Outlook, I set Tools > Options > Mail Format > Internet Format > Automatically wrap text at 132 characters – this is the maximum allowed and should be fine for most URLs. When I sent emails to myself with long URLs it worked fine. However, when I sent emails to other people outside my company, all plain text emails were wrapped at 72 characters – so any URL over 72 characters was broken.
