How do I fix this error?

[abasobito]

I have a problem that this problem appears when the user tries to reset the password on this site: https://mysite.com

It seems that the message is not arriving and I checked the mail it gives me this error:
This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

[email protected]
all hosts for 'gmail.com' have been failing for a long time (and retry time not reached)
Reporting-MTA: dns; SC207-S11.local.localhost

Action: failed

Hey there! The most likely issue is with the DNS or resolvers on your machine. Can you try running this command from your server?

telnet gmail-smtp-in.l.google.com 25

With the situation you describe, that will likely fail. If so, I'd recommend adjusting the /etc/resolv.conf file on your server to use the Google public resolvers, so the file looks like this, commenting out other lines or making a backup before you make changes:

nameserver 8.8.8.8
nameserver 8.8.4.4

and then running these commands to clear the Exim retry database:

/usr/sbin/exim_tidydb -t 1d /var/spool/exim retry > /dev/null
/usr/sbin/exim_tidydb -t 1d /var/spool/exim reject > /dev/null
/usr/sbin/exim_tidydb -t 1d /var/spool/exim wait-remote_smtp > /dev/null

After that you can try sending the message again and you can see if you get a different result or if there are still errors.

where i running this command?

Do you have root access to the server this user is hosted on? If so, you would run that from the SSH terminal as the root user.

If you don't have full root access, you would need to reach out to your hosting provider for additional information on what could be causing that error, as you'll need root access to check the logs and troubleshoot the issue.

Yes i have but i use Terminal and it give me telnet: command not found

 

[cPRex]

Some servers don't have that installed by default. The following command will get that taken care of:

yum install telnet

says no reverse dns in your photo
can you ask your hasting or server provider to create reverse PTR records.
in your image it says the PTR records don't match so you won't get emails sent.
tell them you need correct PTR records show them that photo. who ever owns the IP address you rent from they can do this

Reverse DNS wouldn't be related to the Gmail error he posted in the text. While it likely does need to get addressed, it doesn't seem to be the root cause for this specific issue.

this did not fix the problem bro

The telnet command isn't designed to fix the issue, but that is a tool that will tell us if your server can reach the Gmail network normally. What was the output from that command?

[cPRex]

Thanks for that - that is the root cause of the issue then.

Can you try changing the resolver as I outlined in my first post and then see if the telnet commands works after that change?

 

[quietFinn]

I'd say that the resolver is working, gmail-smtp-in.l.google.com resolves to 173.194.79.26 . and that is Google IP.

[root@finn2 ~]# telnet 173.194.79.26 25

For me it looks like outgoing port 25 is closed.

@abasobito are you able to send emails to any address?

 

[cPRex]

Oh true, nice call, @quietFinn
