Hello, I installed a centos server. I've already been asking things a few month ago about the webmail. I didn't solve it then. I didn't ask further because I wasn't using the server yet. The webmail never worked. But now I need to start to use the server. I am testing the mail, in the ISPconfig panel is monitoring tab showing one services is critical, the smtp-server is critical "offline". I rebooted the server, I restarted postfix, but it looks like it doesn't even want to stop. [root@xxx log]# systemctl stop postfix.service [root@xxx log]# systemctl status postfix.service ● postfix.service - Postfix Mail Transport Agent Loaded: loaded (/usr/lib/systemd/system/postfix.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Mon 2021-08-09 17:33:30 CEST; 2min 28s ago Process: 1634 ExecStop=/usr/sbin/postfix stop (code=exited, status=1/FAILURE) Process: 7488 ExecStart=/usr/sbin/postfix start (code=exited, status=1/FAILURE) Process: 7486 ExecStartPre=/usr/libexec/postfix/chroot-update (code=exited, status=0/SUCCESS) Process: 7482 ExecStartPre=/usr/libexec/postfix/aliasesdb (code=exited, status=0/SUCCESS) Main PID: 1301 (code=killed, signal=TERM) aug 09 17:33:26 xxx postfix[7488]: /usr/sbin/postconf: warning: /etc/postfix/main.cf: unused parameter: maildrop_destination_concurrency_limit=1 aug 09 17:33:26 xxx postfix[7488]: /usr/sbin/postconf: warning: /etc/postfix/main.cf: unused parameter: maildrop_destination_recipient_limit=1 aug 09 17:33:26 xxx postfix[7488]: /usr/sbin/postconf: warning: /etc/postfix/main.cf: unused parameter: maildrop_destination_concurrency_limit=1 aug 09 17:33:26 xxx postfix[7488]: /usr/sbin/postconf: warning: /etc/postfix/main.cf: unused parameter: maildrop_destination_recipient_limit=1 aug 09 17:33:27 xxx postfix/master[7558]: fatal: open lock file /var/lib/postfix/master.lock: unable to set exclusive lock: Resource temporarily unavailable aug 09 17:33:28 xxx postfix/master[7557]: fatal: daemon initialization failure aug 09 17:33:29 xxx postfix/postfix-script[7559]: fatal: mail system startup failed aug 09 17:33:30 xxx systemd[1]: postfix.service: Control process exited, code=exited status=1 aug 09 17:33:30 xxx systemd[1]: postfix.service: Failed with result 'exit-code'. aug 09 17:33:30 xxx systemd[1]: Failed to start Postfix Mail Transport Agent.
ok, I killed postfix and started it again, but the smtp server remains offline.

in the isp-config panel it says the smtp server is down. I tried to configure my mail client to sent mail on port 25 but that would not let me. Also I don't receive mail. Nothing in nothing out.
Start with posting ouput from the test script as explained in https://www.howtoforge.com/community/threads/please-read-before-posting.58408/

ISPconfig now says the SMTP-server is running. Receiving mail works. I have added the mail account for receiving in my gmail account. There is still something, gmail is downloading the mails but I don't see them, but when I search for them I do see them. But sending there won't work. I did something wrong creating the certificate, I get this message: Code: the server returned an error: "TLS Negotiation failed, the certificate doesn't match the host., code: 0"
found this thread, let's see if I can solve this myself https://www.howtoforge.com/communit...-the-certificate-doesnt-match-the-host.84168/ sorry I cannot....... Can you lead me a bit?
Follow https://www.howtoforge.com/securing...server-with-a-valid-lets-encrypt-certificate/ or do a forced update and let it create a cert for your hostname, and use the hostname to connect to your server: Code: ispconfig_update.sh --force
I used: ispconfig_update.sh --force my hostname is nu-vliegen.nl this is not the server name it is a dns-entry. I used that as the name when I was creating the certificate. But I get the same error. Do I need to do something with cache?
The hostname should be a FQDN, so not the full domain, but your domain with a subdomain like server1.example.com.
ok, I tried several things, I updated the certificate 4 times. With <servers-hostname>.my-url.nl, with mail.my-url.nl other things I could think of. But I still get the same error. I can't get is to work.
