The subject is actually higher, with more details. There are approximately 20k emails per week across 27 domains.

In order to ensure security, we require antivirus checks along with various DKIM, DMARC, SPF, and PTR checks.

Additionally, it is important to have a cloud sandbox or the option to connect your own sandbox. This will help identify any potential threats.

Furthermore, having white/gray/black lists in place can enhance the overall security of the system.

Lastly, it is crucial to consider using an antivirus solution other than Avast.

Two notable options for email solutions are iRedMail and Proxmox Mail Gateway.

iRedMail is a comprehensive email server solution that offers features such as integrated antivirus and antispam solutions, along with support for multiple domains and users.

Proxmox Mail Gateway, on the other hand, is a powerful open-source email security solution. It provides protection against spam, viruses, phishing, and other threats, while also offering advanced features like policy-based filtering and quarantine management.

By considering these options, organizations can find reliable and secure email solutions that meet their specific requirements.

We have had a great experience with the team at https://www.spamexperts.com/services/incoming-filtering. They have proven to be reliable and we have been utilizing their services in production for multiple years.

Another option to consider is Zimbra, although it is important to note that it requires a minimum of 8GB RAM to operate effectively.

When it comes to email filtering and management, these solutions offer robust features and can provide the necessary protection for your organization's email communication.

Considering the higher volume of approximately 20,000 emails per week across 27 domains, implementing security measures becomes even more crucial. Performing antivirus checks and implementing DKIM, DMARC, SPF, and PTR checks will help mitigate potential threats.

Utilizing a cloud sandbox or connecting your own sandbox can enhance security by identifying any potential threats through isolation and analysis. It offers an additional layer of protection against unknown or suspicious email attachments and links.

Implementing white/gray/black lists can also contribute to the overall security of the system. These lists can be used to allow or block specific email addresses, domains, or IP addresses based on their reputation or relevance to your organization.

Lastly, diversifying your choice of antivirus solution beyond Avast is a valid consideration. It is important to regularly assess and update your antivirus solution to ensure optimal protection against a wide variety of threats.

Here are some additional considerations for enhancing email security:

1. Two-Factor Authentication (2FA): Implementing 2FA adds an extra layer of security by requiring users to provide two forms of verification, such as a password and a unique code sent to their mobile device, before accessing their email accounts.

2. Encryption: Utilize encryption protocols like Transport Layer Security (TLS) to protect the confidentiality of email communication. This ensures that the content of emails exchanged between your organization and external parties remains secure.

3. User Education: Conduct regular training sessions to educate users about email security best practices, such as avoiding suspicious links or attachments, recognizing phishing attempts, and being cautious with personal information.

4. Spam Filters: Deploy robust spam filters that effectively identify and filter out unsolicited or malicious emails. Regularly update and fine-tune filters to adapt to evolving spamming techniques.

5. Incident Response Plan: Develop an incident response plan that outlines the steps to be taken in case of a security breach or compromise. This helps ensure a swift and coordinated response to limit the impact of a potential incident.

6. Email Retention and Backup: Establish a reliable backup and retention system for emails to ensure that data is protected in case of accidental deletion, hardware failure, or cyberattacks.

7. Regular Security Audits: Conduct periodic security audits to identify vulnerabilities and gaps in your email security infrastructure. This will help you stay proactive in addressing potential risks before they can be exploited.

Here are even more considerations for enhancing email security:

1. Email Authentication: Implement DomainKeys Identified Mail (DKIM), Domain-based Message Authentication, Reporting, and Conformance (DMARC), and Sender Policy Framework (SPF) to verify the authenticity of incoming emails and prevent email spoofing or phishing attacks.

2. Data Loss Prevention (DLP): Deploy DLP solutions to identify and prevent the unauthorized disclosure of sensitive information through emails. This helps protect against accidental or intentional data leaks.

3. Advanced Threat Protection (ATP): Utilize advanced threat protection solutions that leverage machine learning and artificial intelligence to detect and neutralize sophisticated email threats like spear-phishing or zero-day attacks.

4. Security Information and Event Management (SIEM): Implement a SIEM system to monitor and analyze email logs, identify anomalies, and detect potential security incidents in real-time.

5. Email Archiving: Consider implementing an email archiving solution to store and manage historical email data securely. Archiving helps with compliance, e-discovery, and protecting against data loss.

6. Secure Email Gateways (SEGs): Deploy SEGs that act as a protective barrier between your organization's email infrastructure and external networks. They provide additional security features like content filtering, malware scanning, and attachment sandboxing.

7. Regular Patching and Updates: Keep email servers and related software up to date with the latest security patches and updates. This helps address vulnerabilities that could be exploited by attackers.

8. Vendor Assessment: If you rely on third-party email service providers or vendors, conduct thorough assessments of their security measures and practices to ensure they meet your organization's security requirements.
