v6.00.02 Email address validation rollback

Version 6.00.02 of finPOWER Connect introduced an overhaul to how emails are sent within the system. As part of that update, the validation of email addresses was enhanced to use the Gembox validation functions (see: https://www.gemboxsoftware.com/email/examples/c-sharp-validate-email/401)

This validation included the following features:

• Email syntax verification – Checks the format of an email address to see if it conforms to IETF/RFC standards.
• Domain name validation – The DNS protocol checks the email's domain to see if it exists, and an MX record for the given domain is retrieved.
• Email server validation – Uses the SMTP protocol to check the email server's (MX host) connection and availability.
• Mailbox verification – Checks the existence of a specified email address with the email server's report.

While these features are desirable in theory, in practice they caused issues. Specifically, any email address meeting the following criteria would trigger a rejection:

• The recipients email address had been flagged as spam (or blacklisted) at some stage in the past.
• The sender's IP had ever been flagged as spam.

This meant finPOWER Connect would not send the email at all. This limitation had significant effects on customers, as there was a high probability that valid email addresses would fall into these categories.

Upon discussion, it was decided that this level of validation should not be determined by finPOWER Connect and it was decided to re-release v6.00.02 in February 2026. This update reverts the email validation to the original, more basic method (i.e., ensuring an "@" symbol and dots are in the correct places).

This shifts the responsibility for validation back to the email providers rather than finPOWER Connect.

The following systems have been re-released as v6.00.02.16:

• finPOWER Connect
• finPOWER Connect Web Services

The following system did not need to be re-released and remains at v6.00.02.15:

• Though, the release date on the downloads page has been updated to match the others to ensure they are kept together finPOWER Connect Cloud Download.
