Invitations to Bid
ATTENTION MERALCO VENDORS:
A. Low Score and Malicious IP/Domain
To ensure smooth communication during the bidding process, we would like to remind all vendors about MERALCO’s email security controls. These measures are in place to protect our systems and ensure that only secure and reliable emails are received.
- • Delivery of Emails: Emails blocked by MERALCO’s security controls are considered undelivered. If you receive a Non-Delivery Report (NDR) or bounce-back message, please coordinate with your email administrator to resolve the issue and resend the complete email with all required attachments.
- • Cybersecurity Monitoring: MERALCO monitors emails from domains or IP addresses with poor reputation scores. Vendors are advised to maintain good cybersecurity hygiene to avoid email blocking. If an email domain or IP address has a record of poor or low reputation, there is a possibility that the message will be blocked by MERALCO’s security controls.
- • Submission Issues: If your email administrator receives an undelivered report when submitting bid eligibility requirements or proposals to the MERALCO BAC Secretariat and Bid Reception accounts, please contact MERALCO–Supply Chain Management at Meralco_BAC_Secretariat@meralco.com.ph.
• Attachment Guidelines: The maximum email attachment size is 15 MB. For larger files, please compress/zip them or split into multiple emails. Vendors should confirm that each email is successfully delivered.
B. Compliance of Domain Base Authentication
Our Cyber Security Group has implemented additional email security measures to protect Meralco and its employees against cyber threats such as phishing and spoofing. To ensure smooth and uninterrupted email correspondence, please ensure that you are compliant with the following email security protocols:
- 1. For email authentication, a Sender Policy Framework (SPF) record must be added in your Domain Name System (DNS) settings to authorize your servers to send emails on your behalf.
- 2. You must also have a DomainKeys Identified Mail (DKIM) signature to your emails that Meralco’s mail server can verify to ensure the integrity and authenticity of the email.
3. To ensure that your SPF and DKIM settings are working together properly, a Domain-based Message Authentication, Reporting & Conformance (DMARC) policy should be set up to manage unauthenticated emails.
Please be informed that emails that fail to meet these security requirements will be quarantined.
Your cooperation in maintaining the security of our communications is highly appreciated.
