I am unable to receive or send email using the shadowaddress in the from field.  Mail addressed to the shadowaddress (other in this case) goes to the catchall address instead of the user account (steve in this example). 

Mail sent from the shadowaddress gets in Thunderbird:
An error occurred while sending mail. The mail server responded:  5.7.1 <other@example.net>: Sender address rejected: not owned by user steve@example.net. Please check the message recipient steve@rellims.com and try again.

I made the changes to dovecot-ldap.conf as mentioned in other spots:
egrep "^user_filter|^pass_filter"  /etc/dovecot-ldap.conf
user_filter     = (&(objectClass=mailUser)(|(mail=%u)(&(enabledService=shadowaddress)(shadowAddress=%u)))(accountStatus=active)(enabledService=mail)(enabledService=%Ls%Lc))
pass_filter     = (&(objectClass=mailUser)(|(mail=%u)(&(enabledService=shadowaddress)(shadowAddress=%u)))(accountStatus=active)(enabledService=mail)(enabledService=%Ls%Lc))
