Updated again to newer version. this is shown.
define(‘APP_DATA_FOLDER_PATH’, ‘/usr/local/lscp/cyberpanel/rainloop/data/’);
At this rate I believe the only way forward is to just remove that installation of snappymail by renaming the folders here
$ mv /usr/local/lscp/cyberpanel/rainloop /usr/local/lscp/cyberpanel/rainloop_old
$ mv /usr/local/CyberCP/public/snappymail /usr/local/CyberCP/public/snappymail_old
Now run the upgrade script - this will wget the version 2.18.6. It usually removes the old files and installs the new upgrade however just to be sure rename all those folders. See if issue goes away,
I meant this cyberpanel offficial script 02 - Upgrading CyberPanel now you will have to rename all the folders you have setup with the script you just ran
I’ll leave it like that and I’ll try to update
I did the update.
Unsuccessfully
The folders have been restored, but we are still unable to receive emails.
I’m getting worried. I am very grateful for the attention that is with us.
We need to resolve why we are not receiving email
You cannot receive or you do not see any emails in your mailbox via snappymail ?
Do you see any email queue (deferred or otherwise unsuccessfully received) ?
-
Have you tried to pull your emails using a pc client such as Outlook.
-
Did you change anything in your postfix configurations ?
1 - I used pop3 and it pulled only the existing emails and the new ones don’t show either.
2 - I didn’t change anything in postfix
A mystery to solve.
I tried to send an email from gmail.
I don’t understand gmail returned this message.
[dominio.com.br. 99.99.999.999: FAILED_PRECONDITION: connect error (113): No route to host] [mail.dominio.com.br. 99.99.999.999: FAILED_PRECONDITION: connect error (113): No route to host]
I opened port 25 and emails started working again.
However, we cannot leave port 25 open, as it is vulnerable.
How can we use another receiving port?
These are service related issues. Do you have ports open for smtp/smtps ?
Run
# is my firewall ? 25/587
$ iptables -nL | grep 25
# can we ping this port 25/587
$ ss -lntu | grep ':25' || telnet mail.mailserver.com 25How can I make it available only smtps
root@vmi:~# iptables -nL | grep 25
ACCEPT tcp – 0.0.0.0/0 0.0.0.0/0 tcp dpt:25 ctstate NEW,UNTRACKED
root@vmi:~# ss -lntu | grep ‘:25’ || telnet mail.mailserver.com.br 25

Are you using AWS or GCP? What this working before ?
You can disable port 25 using firewalld. To use 587/smtps go to snappymail admin and on left sidebar choose domains. select * and change smtps port
Its. work
Thank you very much for your attention. I am very grateful for the support. So our community goes further.
It is fine.
Do I need to change anything in postfix regarding port 25 to 587?
No you dont need to change anything there. Still having issues ?
