All e-mails sent from Eazy Contracting are sent from the no-reply@eazycontracting.com address to prevent "our" e-mails from being marked (blocked) as SPAM (due to lots of people using PTR records).
To identify which company it's coming from we include the Company Name (Optional) in the "From" field on all outgoing e-mails.
When placing your company name in the "Include Company Name With Outbound E-mails" field under Company Details your e-mails sent will reference your company name.
In the event of Firewalls blocking the address you may need to ask whoever you are sending the e-mail to, to "White List" the @EazyContracting.com domain by their service provider.
