I am in the process of transferring one of our MX services to a new host. During one of the test sessions against live traffic a connection to the final delivery host from the test service could be made. In consequence several messages resulted in a delayed delivery notice. It is these messages for which I am seeing SMTP connection refused from the original sending hosts. The diagnostic information that I have respecting a representative message is reproduced below. I just need to know if this is caused by something I can fix at my end or not. And if so then what the problem is. And if not then why these messages are being refused. In the maillog I see this: Jan 19 12:49:29 mx31 postfix/smtp[81175]: 14FDA745F9: to=<[email protected]>, relay=none, delay=2877, delays=2877/0.02/0.13/0, dsn=4.4.1, status=deferred (connect to alt4.gmail-smtp-in.l.google.com[66.102.1.27]:25: Connection refused) In the defer queue I see this: cat /var/spool/postfix/defer/1/14FDA745F9 <[email protected]>: connect to alt4.gmail-smtp-in.l.google.com[66.102.1.27]:25: Connection refused [email protected] offset=272 dsn_orig_rcpt=rfc822;[email protected] status=4.4.1 action=delayed reason=connect to alt4.gmail-smtp-in.l.google.com[66.102.1.27]:25: Connection refused In the deferred queue I see this: postcat -vq 14FDA745F9 postcat: name_mask: ipv4 postcat: inet_addr_local: configured 3 IPv4 addresses *** ENVELOPE RECORDS deferred/1/14FDA745F9 *** message_size: 7007 318 1 0 7007 0 message_arrival_time: Wed Jan 19 12:01:32 2022 create_time: Wed Jan 19 12:01:32 2022 named_attribute: log_message_origin=local named_attribute: trace_flags=0 sender: pointer_record: 0 named_attribute: dsn_orig_rcpt=rfc822;[email protected] original_recipient: [email protected] recipient: [email protected] pointer_record: 0 *** MESSAGE CONTENTS deferred/1/14FDA745F9 *** regular_text: Received: by mx31.harte-lyne.ca (Postfix) regular_text: id 14FDA745F9; Wed, 19 Jan 2022 12:01:32 -0500 (EST) regular_text: Date: Wed, 19 Jan 2022 12:01:32 -0500 (EST) regular_text: From: [email protected] (Mail Delivery System) regular_text: Subject: Delayed Mail (still being retried) regular_text: To: [email protected] regular_text: Auto-Submitted: auto-replied regular_text: MIME-Version: 1.0 regular_text: Content-Type: multipart/report; report-type=delivery-status; regular_text: boundary="11ACD744F0.1642611692/mx31.harte-lyne.ca" regular_text: Content-Transfer-Encoding: 8bit regular_text: Message-Id: <[email protected]> pointer_record: 0 regular_text: regular_text: This is a MIME-encapsulated message. regular_text: regular_text: --11ACD744F0.1642611692/mx31.harte-lyne.ca regular_text: Content-Description: Notification regular_text: Content-Type: text/plain; charset=utf-8 regular_text: Content-Transfer-Encoding: 8bit regular_text: regular_text: This is the mail system at host mx31.harte-lyne.ca. regular_text: regular_text: #################################################################### regular_text: # THIS IS A WARNING ONLY.
