Aria Operations for Logs Scheduled reports not delivered via Email despite successful SMTP test

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

VMware Aria Operations for Logs is unable to deliver scheduled reports through email, even though the SMTP configuration test and the Send Test Report function in the UI complete successfully. As a result, scheduled report notifications are not received by the intended recipients.

Logs located at /var/log/maillog indicate that the local Sendmail service is timing out when attempting to hand off the mail to the configured relay server.

<Date>:<Time>: Aria-logs-fqdn sendmail[1878]: 61K8Txi4054216: to=<email-id>, delay=4+22:12:15, xdelay=00:00:00, mailer=esmtp, pri=10831945, relay=<relay-server.outlook.com>, dsn=4.4.1, stat=Deferred: Connection timed out with <relay-server.outlook.com>.

Environment

Aria operations for logs 8.x

Cause

Ports 25 and 587, which are typically used for SMTP communication, are blocked or restricted. This restriction prevents the local Sendmail service from successfully handing off emails to the configured relay server.

Resolution

Reconfigure the SMTP settings to use port 2587 with STARTTLS enabled. Refer to the documentation: Configure the SMTP Server for VMware Aria Operations for Logs

 

Additional Information

Amazon SES SMTP supports secure STARTTLS connections on both port 587 and port 2587.
While port 587 is the industry-standard default for email submission, port 2587 can be used as an alternative when firewalls or ISPs block port 587.
