[enhancement] could Auto Archive check network with well know website ? about autoarchivereloaded HOT 4 OPEN

This is an interesting idea. I have not evaluated, yet, if this is possible with the new webextension API...
(Thunderbird >60 will make huge changes to the addon system and it is not worth to develop anything for TB 60)

I think there are some problems with this approach:

• requesting a well known website would be a cross origin request which is blocked by the browser engine included in Thunderbird. Cross origin means, you can only access the domain where your web page is coming from (an addon is not coming from any domain btw.) and domains which allow cross-origin requests. But probably one could find an URL at some CDN provider which allow such success
• reaching a website must not be the same as reaching the mail server, for example one might have a setup where the mail server is in an internal network and it is reachable while public websites are not
• privacy afine people may not like requesting an URL every time you click the archive button

Thanks for your answer. But I know it's easy to open a connexion with JavaScript/TypeScript.
If you're able to read mail server config file, you just have to open a connexion (without exchanging anything) and close it : if timer goes in timeout, don't try archive, else network is up.
My knowledge is better in networking.
For example, if server is imap.domain.extension on port 587, you can open a connexion, even if you're not able to use the protocol behind. That way, you're sure about server status

With which js command would you open the connection to IMAP/POP3 server?
