> Good morning all.
> I'm facing with a strange problem with PHP sockets and POSTFIX:
> 1) I have a Postfix machine that runs very well for sending/receiving
> emails to/from outside (via Outlook)
> 2) I'm working on a CRM software that connect to this Postfix via PHP
> socket_connect function. Well, now:
> a. all socket connection to this Postfix from a machine outside my
> cloud network, are ok (I can connect and interact with smtp)
> b. when try to connect to Postfix with the same script used in 1) but
> installed on a machine on the "same cloud network". I obtain a Tiimeout
> error from PHP socket_connect.
> 3) When "telnet-ting" this Postfix on port 25, is all OK from outside
> and from inside cloud network, that is: I can connect via telnet to smtp
> also from the machine in (b)
> Any idea why ? Here below my MAIN.CF file
