Problems on other RedHat linux servers / Re: I can send and receive messages via the web, but it doesn't work through the...
« on: January 24, 2025, 08:52:20 AM »Various caching schemes are in play, but shouldn't affect anything in this case.
Have you tried testing your server with telnet and see if you can get through the firewall and services are listening (postfix)?Code: [Select]telnet your.domain.com 25
telnet your.domain.com 465
telnet your.domain.com 587
Hi,
Thanks, all ports connect with telnet, but only on 25 and 587 does Postfix return ESMTP, on 465 it returns nothing...
Ncat I could not access it....
nc -vz google.com 80 - it returned me -bash: nc: command not found

« on: January 23, 2025, 07:06:52 PM »Does your SSL have the mail sub-domain added?
Most mail clients like Thunderbird will automatically contact the email server for the correct settings.
The error is it can't connect to the SMTP server via SSL.
Make sure ports 486 and 587 are open, as these are the SMTP SSL ports. Port 25 is Non-SSL.
Hi,
1. Yes, there is a mail subdomain added...
2. I mention port 25 because when I didn't select SSL for the mail client, I send through it without problems. and accordingly I receive through port 110...
3. For SSL, my port is 465 and it is open...
Does the CWP have a cache?

Hi,
I fixed the rDNS/PTR record and it's OK...
I have completed all the settings, including SSL, and created an email account, I can send and receive messages via the web (Roundcube Webmail) and port 25 and 110, but it doesn't work through the email client when I use the corresponding SSL ports, where am I wrong?
When setting up email to work with SSL, I get this error:
ERROR:SMTP Connect host=mail.xxxxxxxx.com error=Error connecting with SSL.
error:00000001:lib(0):func(0):reason(1)
Thanks in advance!

Other:
I deleted a user and creating a new user several times due to some problems and now we get to:
rDNS/PTR = FAILED, check with your hosting provider! FAILED
I have talked to my provider, this rDNS worked before when I used Centos 7, now at the beginning with AL 9, but when deleting and creating a new user it was lost...at that moment I noticed it...
Thanks in advance!

« on: January 19, 2025, 08:57:36 AM »You need forward and reverse DNS, both agreeing in order to be considered a valid sending source for other servers to accept mail. It should not be tied to a particular user account. What is the server's FQDN?

« on: January 19, 2025, 08:54:59 AM »Def. an encryption problem -- not able to establish a secure connection. Is your Roundcube still set for defaults? Is it checking with SSL/TLS or STARTTLS? Roundcube checks the localhost, but mail ports may not be open for remote connections. What CSF ports do you have open for mail? Incoming: 143, 993, 995? Outgoing: 25, 465, 587?

Hi,
the server uses Alma Linux 9, I deleted a user several times due to some problems and now we get to:
rDNS/PTR = FAILED, check with your hosting provider! FAILED
I have talked to my provider, this rDNS worked before when I used Centos 7, now at the beginning with AL 9, but when deleting and creating a new user it was lost?
What should I do?
Thanks in advance!

Problems on other RedHat linux servers / Re: the sequence of settings...?
« on: January 15, 2025, 05:09:11 PM »I think AWS Monster's guide/notes is a good reference:
https://www.awsmonster.com/cwp-installation-and-configuration_12
https://www.awsmonster.com/part-1-cwp-basic-configuration-after
https://www.awsmonster.com/part-2-cwp-basic-configuration-after
I've been tempted to create something for my own reference and for the good of others, but I would have to wait until I next set up another CWP server.
Starburst?
Hi,
thank you very much, I have looked into it, very useful guide...

Problems on other RedHat linux servers / Re: daily "Anacron" messages?
« on: January 15, 2025, 05:02:53 PM »Did you change the default php.ini to be more "chatty" about errors? It is printing NOTICE errors to your output, but they are just notices, not fatal errors.
https://phoenixnap.com/kb/php-error-types
Do you have this in your php.ini:Code: [Select]error_reporting = E_ALLInstead, try:
display_errors = OnCode: [Select]error_reporting = E_ERROR
display_errors = Off
Hi,
Thank you very much for the recommendation...It's true that I should also disable error reporting, but it worries me a little that these current error reports are related to diagnostics and backups, with CentOS 7 it reported that it had made a daily, weekly, etc. backup...?
I also notice that it makes a daily backup for a user that I deleted a few days ago, and today I'm with a different user, maybe some kind of cache?
Thanks in advance!
