IMAP / POP3
Test tilgang til postboksen: pålogging, funksjoner, mapper og STARTTLS.
Test IMAP-pålogging
Logger på en postboks og lister mappene: kontrollerer tilgjengelighet, påloggingsinformasjon og tillatelser på én gang.

IMAP-funksjoner
Viser funksjonene serveren annonserer, inkludert støttede autentiseringsmetoder (AUTH=PLAIN, AUTH=XOAUTH2 ...).
