Options

New in version 2.5: The strict option was introduced in Symfony 2.5.

strict

type: boolean default: false

When false, the email will be validated against a simple regular expression. If true, then the egulias/email-validator library is required to perform an RFC compliant validation.

message

type: string default: This value is not a valid email address.

This message is shown if the underlying data is not a valid email address.

checkMX

type: Boolean default: false

If true, then the checkdnsrr PHP function will be used to check the validity of the MX record of the host of the given email.

checkHost

type: Boolean default: false

If true, then the checkdnsrr PHP function will be used to check the validity of the MX or the A or the AAAA record of the host of the given email.
