when user add a new email account that not are provided by a big vendor should inseret imap and smtp servers by hand… but there are e way described by some RFCs to guess sever address,

please consider to discover via SRV records begin with:


see RFC 6186, 8314, 8553 and others

I’m not sure a lot of providers use SRV records TBH

this is not the point; ISP (like me) starting use xml file for autoconfig thunderbird (not standard), but already now Outlook app read SRV record (see my test attached where I insert only email and password to configure account)

app should starting read SRV as described in RFC and ISP they will have a chance to do their part
