This problem can be reproduced in one second. Here you go:

protocol lmtp {
     mail_plugins = $mail_plugins sieve imap_quota
}

Mar 29 13:13:33 mail dovecot: lmtp(25315): Connect from local
Mar 29 13:13:33 mail dovecot: lmtp(gedalya at gedalya.net): Error: Couldn't 
load required plugin 
/usr/lib/dovecot/modules/lib11_imap_quota_plugin.so: dlopen() failed: 
/usr/lib/dovecot/modules/lib11_imap_quota_plugin.so: undefined symbol: 
command_unregister

Simple: imap_quota is not a plugin for lmtp, it is a plugin for imap. 
Notice the last bit of the error message. It won't work just like you 
couldn't dynamically load it into LibreOffice or whatever.
