Hi.
I was wondering how do popular clients (like Mail.app) detect what the settings
should be for an email client when you initially enter the email address.
Does anyone know how it tries to detect this stuff?
I’m trying to set up my email server so that users don’t need to go through the
painful manual configuration.
Thanks,

This is Thunderbird's approach:
/**
* Try to guess the config, by:
* - guessing hostnames (pop3.<domain>, pop.<domain>, imap.<domain>,
* mail.<domain> etc.)
* - probing known ports (for IMAP, POP3 etc., with SSL, STARTTLS etc.)
* - opening a connection via the right protocol and checking the
* protocol-specific CAPABILITIES like that the server returns.
*
* Final verification is not done here, but in verifyConfig().

See: mailnews/base/prefs/content/accountcreation/guessConfig.js in the
source.
