I have setup CyberPanel twice on gpc with same webmail problem cannot send mail or do anything on the webmail.

can someone help me out

Here is mylog for journalctl -f | grep dovecot

#2

try to create a user account then send email from that user account. it looks like permission error. i have seen similar post on the forum with solution

#3 
Try this: Append new settings below in /etc/dovecot/dovecot.conf, then restart dovecot service and try again.

service stats {
    unix_listener stats-reader {
        user = vmail
        group = vmail
        mode = 0660
    }

    unix_listener stats-writer {
        user = vmail
        group = vmail
        mode = 0660
    }
}

I have tried this, create another user account, Rainloop pretend as if it send email but nothing happen.

What has failed or failing
=> Email folders are not created with new email account
=> I cannot manually create them either
=> I cannot sent email as well

Just as @jobayer stated above, it persision issue but I don’t know how to fix this and I do not want to just chmod 777 any folder I don’t understand

#6

Update:
I have chmod 777 the vmail dir (which I want to avoid, had tried 755 before)
=> I can receive email
=> Sent mails are not delivered
Here is out of journalctl -f | grep postfix mr_goodmuyis@vps1:~$ journalctl -f | grep postfixOct 12 12:51:07 vps1 postfix/ - Pastebin.com

Update 2:

=> I can also send and receive email with the same domain

Should be able to do this to fix ownership and perms. My perms are 755 for directories and 640 for files.
chown -R vmail:vmail /home/vmail
chmod 755 /home/vmail
find /home/vmail -type d -exec chmod 0755 {} \;
find /home/vmail -type f -exec chmod 0640 {} \;

Might have to restart dovecot after doing.

@whattheserver that works I have reverted back to vmail to 755
Thank you

Am also working on mail delivery issue, any idea Please?

=> Firewall: port 26 used as an alternative

telnet connection on port 25 into the instances was successful
telnet connection on port 25 out of the instances was unsuccessful

Been there done this with Google. wasted hours setting up stuff and then got all the way to email and wasted hours before i realized it was blocked…

Google Cloud doesn’t allow SMTP over port 25 which means you will get 0 inbound email as this is by default going to arrive from external server via port 25. :frowning:

You can send email via another port 2525 port etc but inbound will always be an issue. This one of the reasons I personally won’t use Google cloud and pay for their Gsuite just to have email. The cost of email alone elsewhere plus the hassle of configuration I could pay to have my stuff hosted somewhere without default email blocked with a forced upsell to use.

see the below for reference.

If you need KVM VPS hosting I can hook you up in NL. If you need another location I highly recommend Vultr’s cloud which has email ports unblocked by default and is very reliable.

I use Vultr for my WHMCS/Support so it’s not hosted in the same DC as my client’s stuff in event DC ever were to have an issue.
