Open Source Unified Secure Email Gateway
Hermes Secure Email Gateway is a Free Open Source Ubuntu 18.04 Server based Email Gateway that provides Spam, Virus and Malware protection, full in-transit and at-rest email encryption as well as email archiving. It features the latest email authentication techniques such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting and Conformance) in order to combat email spoofing, phishing, scams, email compromise attacks and spam.
Hermes Secure Email Gateway combines Open Source technologies such as Postfix, Apache SpamAssassin, ClamAV, Amavisd-new and CipherMail under one unified web based Web GUI for easy administration and management of your incoming and ougoing email for your organization.
It can be deployed to protect your in-house email solution as well as cloud email solutions such as Google Mail and Microsoft Office 365.
Hermes SEG can be easily installed in your existing Ubuntu 18.04 server machine by utilizing the ubuntu_hermes_1804_install.sh script. The script requires that you have a fully updated Ubuntu 18.04 server installation and that you have a /mnt/data directory for database and email archive storage.
The script will prompt you for the following information before it starts installation. Ensure you have that information available before you begin:
The Configure /mnt/data partition directions below assume you have a 250GB secondary drive which you will partition, format and mount as /mnt/data.
Technically a secondary drive for the /mnt/data directory is not a requirement but it's highly recommended for performance reasons. If you don't wish to use a secondary drive for the /mnt/data directory, simply create a /mnt/data directory in your system and skip to the Quick script install and run instructions section.
Configure /mnt/data partition
sudo mkdir /mnt/data
sudo fdisk -l
Look for 250 GB drive you created earlier device ID, usually /dev/sdb. Ensure you select correct device ID before running the commands below)
sudo fdisk /dev/sdb
sudo mkfs.ext4 /dev/sdb1
Mount Partition to /mnt/data
sudo mount /dev/sdb1 /mnt/data
Get disk UUID
ls -l /dev/disk/by-uuid
sudo vi /etc/fstab
Add the following in /etc/fstab where DEVICE_ID is the UUID from the command above
UUID=DEVICE_ID /mnt/data ext4 errors=remount-ro 0 1
Verify drive is mounted
sudo df -h
Should yield output similar to below:
Filesystem Size Used Avail Use% Mounted on udev 1.9G 0 1.9G 0% /dev tmpfs 395M 1.1M 394M 1% /run /dev/sda2 79G 5.5G 69G 8% / tmpfs 2.0G 0 2.0G 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup /dev/loop0 87M 87M 0 100% /snap/core/4917 /dev/loop1 90M 90M 0 100% /snap/core/8039 tmpfs 395M 0 395M 0% /run/user/1000 /dev/sdb1 246G 61M 233G 1% /mnt/data
Reboot and ensure /mnt/data gets mounted automatically
