🧩 Autodiscover Functions

myl-discovery exposes several functions to discover email settings:

• autodiscover: This function wraps the below function do automatically detect the right settings. (See Autodiscover strategy for more information)
• autodiscover_srv: This function attempts to resolve SRV records for the domain to discover IMAP and SMTP servers.
• autodiscover_exchange: This function attempts to use the Exchange Autodiscover service to discover email settings. It requires a username and password.
• autodiscover_autoconfig: This function attempts to fetch and parse an autoconfig XML file from a URL specified in the domain's TXT records.
• autodiscover_port_scan: This function performs a port scan on the domain to discover open IMAP and SMTP ports.

🧠 Autodiscover Strategy

The autodiscover function uses the following strategy to discover email settings:

1. It first attempts to use autodiscover_autoconfig to discover settings from an autoconfig/autodiscover URL specified in the domain's TXT records.
2. If that fails, it attempts to use autodiscover_srv to discover settings from the domain's SRV records.
3. If that fails and a password is provided, it attempts to use autodiscover_exchange to discover settings using the Exchange Autodiscover service (only if credentials were provided)
4. If all else fails, it uses autodiscover_port_scan to discover settings by performing a port scan on the domain.
