I'm a little confused here. The directory structure doesn't actually follow in my bitnami setup.
When I go into /opt I only have /espcocrm5.0.5-0 as a possible folder, I don't have any 'bitnami' folder, so the second path, from what I can tell, wouldn't do anything. I also don't have a /bitnami folder in the root directory.
Am I missing something, still can't receive incoming emails, outgoing is fine.
Also, when I used this resource:
I got this:
crontab -u bitnami -e
crontab: user `bitnami' unknown
