Hello, I did a clean installation of ISPConfig 3 following all the steps provided here: https://www.howtoforge.com/perfect-...sl-pureftpd-bind-postfix-doveot-and-ispconfig The server is going good but I've got a problem I cannot solve by myself: all the emails sent via PHP mail() function aren't delivered. I double checked both inbox and spam directory and nothing arrives from the server. At the same time, no particular error is raised by PHP. I've searched both in "google" and in this forum but I cannot figure out how to solve this problem. What I already did Checked if the port 25 is open and reachable. And it is. Changed the Courier/Dovecot option in ISPConfig panel, system -> serve config -> myserver -> mail Followed those steps, but I think it's not regarding my problem: https://www.howtoforge.com/community/threads/php-mail-not-working.56564/ Testing recursively with a simple mail() function, that shows no error.

Seems as if port 25 outgoing (not incoming) is blocked. Do you run the server in a datacenter or at home or in office? When the server is not in a datacneter, then your internet access provider blocks port 25 to external servers.
I did a quick check but, maybe I am wrong, the outgoing port seems not blocked. Code: root@vultr:~# telnet myhostname.tld 25 Trying 107.XXX.XXX.XX ... Connected to myhostname.tld. Escape character is '^]'. 220 myhostname.tld ESMTP Postfix (Ubuntu) helo myhostname.tld 250 myhostname.tld quit 221 2.0.0 Bye Connection closed by foreign host.
Then you should talk with your dataceter. If you cant reach the google mailserer on port 25 with telnet, then your mailserver (postfix) cant reach it as well and this is not a server config issue in your mailsystem.
Unfortunately, the cache flushing has no effect. This is my resolv.conf, maybe it helps. Code: root@vultr:~# cat /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 108.61.10.10 nameserver 2001:4860:4860::8888 nameserver 2001:4860:4860::8844
