SMTP_BLOCK disabled but still seems to be blocking

[tbenoit]

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.

Maybe to late for this reply, but what fixed this issue for me was to allow the SMTP server IP address in csf.allow.
However when I did this for some reason it periodically reblocks it and I have to restart CSF. I'm looking for a solution to that now.
