Mail Validator

Description

The Mail validator action checks if an email address is valid.

When the check passes the success hop will be followed, otherwise it will go to the fail hop

Options

Option	Description
Action name	The name of the workflow action.
Email address	The email address, or list (separated by spaces) that have to be checked.
Settings
SMTP check	By default, Apache Hop will only check email address structure (using regular expression). If you want to perform a SMTP check, please select this option and fill Email sender (see after). Hop will extract domain name from the supplied email address (to check) and will try to get all exchangers from the domain name. Each exchanger will be queried on port 25.
Time out	In order to perform a SMTP check, Hop will open a socket on the target SMTP host. Specify here the socket time out in milliseconds (0, the default: no time out).
Email sender	If you select the "SMTP check" option, this field is mandatory. Hop will need sender email address to query SMTP host.
Default SMTP server	If you know which SMTP server to query, please specify it here, Hop will then query only this one.

Result	Value
True	Every address in Email address is valid, with 0 errors. With SMTP check, a mail server also accepted Email sender and each address.
False	The number of errors is 1. Email address is empty, an address is not a valid email address, SMTP check is selected while Email sender is empty, or with SMTP check the mail server refuses Email sender or an address, the domain doesn’t exist or has no MX or A record, or the server can’t be reached. The addresses are checked one after the other, and the first one that is not valid ends the check.
Result files	Passed on unchanged.

The addresses must be separated by exactly one space: two spaces, or a comma, make the check fail.

SMTP check connects to port 25 of the mail servers of the domain (its MX records, or its A record when it has no MX record), or of Default SMTP server when it is set, and asks whether it accepts Email sender and the address.
