Reproduction: 1. File | New | Existing Mail Account... 2. Configure foo@gmx.net Actual result: IMAP and SMTP servers are set up FileLink is not set up, you need to set up another account Expected result: IMAP and SMTP servers are set up FileLink is configured to use the WebDAV service included in the email account (of gmx.net, web.de, and countless others) Importance: I can use FileLink right away, without extra setup work. Implementation: 1. Add section for <storage> in the autoconfig XML file type 2. Add the information to the ISPDB for all big providers which offer that using standard protocols. (That includes how to share a file with others and get the public URL for it.) 3. Let the Account Setup Wizard use the information to set the prefs for FileLink 4. Consider whether we need any confirmation UI or not. (security, i.e. not exposing passwords to attacker servers, if the data in the XML was hostile)
