Unable To Send Email To A Dynamic Group - Error Is "Sizelimit Exceeded" (Doc ID 1281300.1)

Last updated on AUGUST 25, 2017

Applies to:

Oracle Communications Messaging Server - Version 5.2.0 and later
Information in this document applies to any platform.

Symptoms

Mail sent to a dynamic group does not arrive and and the following error appears in the mail.log_current file:

15-Dec-2010 14:10:26.78 3bf.91.434 tcp_intranet QE 2 john.doe@foo.com rfc822;dynamic_grp_name@foo.com @msg-store.foo.com:dynamic_grp_name@foo.com <4D08BDD7.2010104@foo.com> mailsrv dns;[10.7.7.10] (msg-store.foo.com -- Server ESMTP [Sun Java[tm] System Messaging Server 6.3-6.03 [built Mar 14 2008; 32bit]]) smtp;451 4.5.0 error opening file/URL referenced by alias: dynamic_grp_name@foo.com@msg-store.foo.com:dynamic_grp_name@foo.com: smtp;451


Sending mail like this used to be successful, but for some reason now, it is failing.

It was also noticed that an error was returned when issuing the following command:

#  imsimta test -rewrite -debug -from=john.doe@foo.com dynamic_grp_name@foo.com


(In this case the -from= was required because this particular dynamic group had a mgrpAllowedBroadcaster attribute, but the issue is not specific to that type of group).

In the imsimta test -rewrite -debug output, we found:

<snip>

11:47:30.02: Performing URL search on: ldap:///o=foo.com,dc=foo,dc=com?mail?sub?(&(objectClass=inetmailuser)(mail=*foo.com))
11:47:30.84: Search failed: Sizelimit exceeded (4)
<snip>

Changes

The number of users defined in LDAP has grown gradually over time.
