Summary:                    dovecot crashes on Solaris 11 i386 with "wrong ELF
class: ELFCLASS32"
Description: 
package CSWdovecot 2.2.21,REV=2015.12.13 installs successfully on Solaris
11 i386, but the binaries can not access their dynamic libraries.

"uname -a":
SunOS surz115 5.11 11.3 i86pc i386 i86pc
"file /opt/csw/sbin/dovecot":
/opt/csw/sbin/dovecot:  ELF 32-bit LSB executable 80386 Version 1 [FPU],
dynamically linked, not stripped, no debugging information available
"ldd /opt/csw/sbin":
libc.so.1 =>     /lib/libc.so.1

the dovecot binary starts nevertheless, but connecting to imap-login leads
to error-log:
Error: Couldn't load required plugin
/opt/csw/lib/dovecot/lib15_notify_plugin.so: dlopen() failed: ld.so.1:
imap: fatal: /opt/csw/lib/dovecot/lib15_notify_plugin.so: wrong ELF class:
ELFCLASS32

Is there something wrong with the compilation of the package?

Thanks for any help

The issue you are facing has a different cause that what you think. The
binaries in /opt/csw/bin and /opt/csw/sbin are actually copied of
/usr/lib/isaexec which execute the optimized version from an
isa-subdirectory. The binary invoked is

I suppose you are using the wrong path in your configuration file, e.g.
  mail_plugin_dir = /opt/csw/lib/dovecot
instead of the correct
  mail_plugin_dir = /opt/csw/lib/64/dovecot
