I'm sure I'm missing something simple...
I have SMTP_BLOCK disabled:
SMTP_BLOCK = "0"
I can manually open a connection to my SMTP Server over Port 465 from the command prompt, which tells me iptables is allowing outbound connections properly.
# iptables -L | grep -i smtp
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:smtp
However, a script fails to connect to my SMTP server (SMTP using ssl over Port 465) with CSF enabled. If I disable CSF the script works, but re-enable CSF and the script fails again. I also tried it with CSF enabled but LFD disabled.
Any assistance is appreciated.
