Overview

Members report that emails they send to one of your Lists do not get sent out to the List members. Checking the recipient's sending log reveals a large number of retry entries like the following:

Wed, 17 Feb 2021 21:31:31 Sending email to: username@domain.com
<-- DNS info available for: Relay Host
--> Attempting to connect to: Relay Host (xxx.xxx.xxx.xxx 2525)
<-- Connected to: Relay Host (xxx.xxx.xxx.xxx 2525)
<-- 220 mx.subdomain.com ESMTP
--> HELO lists.domain.org
<-- 250 mx.subdomain.com
--> MAIL FROM: member@domain.org
<-- 250 sender <member@domain.org> ok
--> RCPT TO:<username@domain.com>
<-- 250 recipient <username@domain.com> ok
--> DATA
<-- 354 go ahead
--> (message body)
--> Scatter write failed.
--> QUIT

Or, checking the debug logs you find entries similar to:

20210119 131249 Warning General nb_socket::nb_scatter_write received socket error: 14
20210119 131258 Warning General writev failed. Errno = 14, error message = "Bad address"

Solution

This is a known issue with Lyris LM version 12.4. To resolve this issue, upgrade to 12.4.1.

1. Download and install the appropriate version for your OS and database configuration
2. After installation, ensure that the following services have started. Manually start any services that did not automatically start:
   • List Manager
   • List Manager Web
   • Frontend HTTP Daemon

After the upgrade to version 12.4.1, mailings that were queued are immediately sent and new mailings are not delayed.
