Problem with the mail box

mymmo73 · Oct 16, 2020

Hi, I state that I do not understand anything about linux, I improvised to install ispconfig following a tutorial, I must say that everything went well except the e-mail part, however I try to expose my problem translated with the translator hopefully well. I installed ISPConfig Version: 3.1.15p3 on debian I set up an email account with rondocube I can send mail regularly but I cannot receive. When I send a message to the mailbox I have configured, it returns the following message:

"Reason: This is the mail system at host smtp-36.iol.local.I am sorry to have to inform you that your message could not be delivered to info@tradingforum.it. The message is attached below. The remote mail system said: 554 5.7.1 <info@tradingforum.it>: Relay access denied "

I entered my provider's panel and configured the record and configured an MX record that points to my FQDN (xxx.xxx.it). My provider's assistance confirms that the configuration is ok. I went around a lot on the forums I saw that there are many open discussions about my problem, but I could not solve it anyway, if something can help I tried to run some commands:

You added windows characters in the file, remove the ^M from master.cf and restart postfix.

thanks for your quick reply, I don't know how to modify the file, I would be grateful if you could give me some suggestion ..

Did you restart postfix afterwards?
systemctl restart postfix

mymmo73 · Oct 16, 2020

yes i ran this command
Code:
# postfix stop && postfix start
but nothing to do, do i have to use another command?
I also ran this command
Code:
$ systemctl restart postfix

Th0m · Oct 16, 2020

I see the # before tlsproxy is removed, it should be there
Run
Code:
systemctl restart postfix
And please follow the install steps closely, so you don't comment out things that shouldn't be, and vice versa.

And if you want to further test your system, login to webmail on your server with an account that you created in ISPConfig and send an email to the same account. The email should arrive within a few seconds in your webmail client. if not, check the mail.log file and post the lines that got added for this email sending attempt.

I did as you said the email arrived in seconds ..

mymmo73 · Oct 16, 2020

how do i proceed now?

Jesse Norell · Oct 16, 2020

Send yourself an email from outside, eg. from gmail or something, and post the logs which show up in mail.log when you do so. Also post your full main.cf and master.cf.

If that's all you have in your mail log when you sent yourself an email, it never made it to your server. Maybe you have a firewall problem, on your server or at upstream at your provider? (Some vps hosting companies block port 25 by default.) That's quite different than the 'Relay access denied' error you said you got initially.

I contacted my web server provider and they replied "We do not have any kind of firewall in front of our cloud servers" then I contacted my domain provider and they replied "we don't block door 25", like can I do to solve this problem?

firstly, this line in your main.cf file is wrong:

myhostname = webitalia.it
Click to expand...

judging by your current dns records, and the lack of pop/pop3/imap/smtp/outbound/mail subdomain entries, i'd say the correct hostname should be incoming.webitalia.it, so there's a good chance /etc/mailname is wrong as well.

secondly, testing from the cli, access to port 25 is fine.
Code:
telnet incoming.webitalia.it 25
Trying 80.83.161.2...
Connected to incoming.webitalia.it.
Escape character is '^]'.

it looks like that mailserver doesn't believe it's responsible for the domain tradingforum.it, if it was, and that mailbox didn't exist, i would expect the response to be:
Code:
550 5.1.1 <info@tradingforum.it>: Recipient address rejected: User unknown in virtual mailbox table

yes, my FQDN is incoming.webitalia.it, I don't know if it can help I launched the following command and it returned the following result:
Code:
root@webitalia:~# less /etc/mailname
webitalia.it
