The recipient server did not accept our requests to connect

[Sekar C]

We are using 1.3.0 build 955(Linux Mailpiler 4.10.0-42). Recently we started facing an issue, All emails are not delivering to piler server and rejected by mailpiler. Getting and error “The recipient server did not accept our requests to connect. Learn more at <a href="https://support.google.com/mail/answer/7720" target="_blank">,https://support.google.com/<wbr>mail/answer/7720</a>>
The receiving host refused the connection from our servers. Please let me know how to fix this.

[Janos SUTO]

I’m confused. Who didn’t receive the message from who?

[Sekar C]

From Gsuite server to mailpiler

[Janos SUTO]

OK. Then show me the logs regarding the delivery issue.

[Sekar C]

I’ve already attached the logs from gsuite server. Could you please help me on where can i find the delivery status logs on mailpiler server.

[Janos SUTO]

It’s not a log, merely an error message. Piler syslogs its info to the mail log. Find it in /var/log directory.

[Janos SUTO]

No news is good news.

[Former user]

Same issue. I’m very new to piler and I did not install it my self. I did not find any useful logs in /var/log/. Which file is?

‌

I followed that directive but I suppose my Piler server is not well configured: https://www.mailpiler.org/wiki/current:google-apps-for-business

[Janos SUTO]

The mail log. The exact piler depends on your distro, eg. maillog or mail.log.

Google do not reach the server…

Which port google use to contact Piler?

[Janos SUTO]

The usual method should be smtp delivery from google mail to piler, so check out the port 25 traffic and access on the piler host.

[Former user]

I found out my internet provider block the port 25 and I got hard time to find out we can route email to a different port.

1. Add Host: https://support.google.com/a/answer/2614757?hl=en
2. Change route. The option above the change envelop recipient option

[Janos SUTO]

So is it okay by now?

[Former user]

Yes, I started to receive emails. Thanks
