S 09:25 0:00 /usr/sbin/postdrop -r I have made a new clean wordpress install, tried to reset password, and nothing works when trying to do such. In console on ps aux I can see the above processes. Thats all there is visible.

check your firewall, some server provider default blocked sendmail function (e.g. port 25)

I have no extra firewall functions deployed.

And my dedicated servers are not locked.

test your sendmail on ssh echo "Subject: sendmail test" | sendmail -v your@email.com

[root@apa centos]# echo "Subject: sendmail test" | sendmail -v cosmin@uhlhost.net postdrop: warning: mail_queue_enter: create file maildrop/652695.1169380: No such file or directory postdrop: warning: mail_queue_enter: create file maildrop/653160.1169380: No such file or directory

try kill postdrop and sendmail process kill -9 $(ps -auwx | grep postdrop | gawk -F' ' '{print $2}') kill -9 $(ps -auwx | grep sendmail | gawk -F' ' '{print $2}') restart postdrop and sendmail service postdrop start service sendmail start

Very weird behaviours: [root@apa centos]# service postdrop start Redirecting to /bin/systemctl start postdrop.service Failed to start postdrop.service: Unit postdrop.service not found. [root@apa centos]# service sendmail start Redirecting to /bin/systemctl start sendmail.service Failed to start sendmail.service: Unit sendmail.service not found. [root@apa centos]#

it seems there is some issues on amavis cant start.

[deleted] Have you tried reinstalling it?

[deleted] For me restarting the VPS solves the problem for a time. I'll keep testing to see how much time.

Log in and test. Error is present after total VPS reboot. It was working fine for just about 2 hours after VPS reboot.
Made the change request_terminate_timeout = 0 I restarted the PHP but the error is still present.
504 Gateway Time-out
Rebooted Nginx and Php = the error is still present.

I have on this VPS Nginx 1.19.2 it's safe to downgrade to 1.17?

[deleted]

@aaPanel_Jose still no fix to this?

[deleted] 18 hour later after request_terminate_timeout = 0 + VPS reboot, Sendmail still works. I'll monitor this further and get back with feedback.
