Error 550 sending outbound messages

Post by kylemcisaac »

Hi all,

I am trying to set up my mail server and testing inbound and outbound mail. Receiving inbound mail works fine, however, sending out it doesn't let me, getting the following message back:

Code: Select all

MailEnable: Message could not be delivered to some recipients.
The following recipient(s) could not be reached:

Recipient: [SMTP:my-personal-gmail-account@gmail.com]
Reason: Remote SMTP Server Returned: 550 Relay not permitted



Message headers follow:

Received: from ([192.168.2.167]) by nsktech.ca with MailEnable WebMail; Tue, 7 Jun 2022 22:55:37 -0230

From: <contact@ourotherdomain.ca>
Subject: Test 3

Message-ID: <A0117E22948848609A27807A0A3548EC.MAI@nsktech.ca>
MIME-Version: 1.0
X-MimeOLE: Produced By MailEnable WebMail.NET V2.0.0.0
X-Mailer: MailEnable WebMail.NET
Content-Type: multipart/alternative;
boundary="__=_AltPart_2120624282_1606874438"
Any ideas of what I need to do to get this working? Nobody will be using direct IMAP/SMTP in clients, just exclusive to Webmail.

Thanks,
Kyle

Hi,

Have you reviewed the following article and checked off the prerequisites for sending to large providers such as Gmail etc? The main ones are PTR, DKIM and SPF.
