4. System Tuning for v6.0r3
To ensure stability under load, the following kernel and system parameters were applied in /etc/sysctl.conf (critical for v6’s event-driven architecture):
# PowerMTA v6 optimizations
net.core.rmem_max = 134217728
net.core.wmem_max = 134217728
net.ipv4.tcp_rmem = 4096 65536 134217728
net.ipv4.tcp_wmem = 4096 65536 134217728
net.ipv4.ip_local_port_range = 1024 65535
net.core.netdev_max_backlog = 50000
fs.file-max = 2000000
Applied with: sysctl -p
10. Verify Installation
-
Check service status:
sudo systemctl status pmta -
Check logs (/var/log/pmta or system journal):
sudo tail -f /var/log/pmta/pmta.log -
Test SMTP connection:
telnet 127.0.0.1 25Expect SMTP banner from PowerMTA.
-
Send a test message via SMTP or use pmta command-line tooling to queue a test message.
