Hello David, Well, it seems to work from one Homebox to another, for instance: Here the server logs: ---------------------------------- > Apr 05 19:20:46 portal postfix/qmgr[21470]: 6AC3240807: > from=<an...@rodier.me>, size=3066, nrcpt=1 (queue active) > Apr 05 19:20:46 portal clamsmtpd[14542]: 10004D: from=an...@rodier.me, > to=andré@homebox.space, status=CLEAN > Apr 05 19:20:46 portal postfix/smtp[30761]: 1FCA540467: > to=<andré@homebox.space>, relay=127.0.0.1[127.0.0.1]:34001, delay=1.4, > delays=0.73/0.02/0.07/0.59, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued > as 6AC3240807) > Apr 05 19:20:46 portal postfix/smtpd[30763]: disconnect from > localhost[127.0.0.1] ehlo=1 xforward=2 mail=1 rcpt=1 data=1 quit=1 > commands=7 > Apr 05 19:20:46 portal postfix/qmgr[21470]: 1FCA540467: removed > Apr 05 19:20:46 portal dovecot[12813]: lmtp(30766): Connect from local > Apr 05 19:20:46 portal dovecot[12813]: lmtp(andre): > WGTdAo6qp1wueAAAeNB+QA: sieve: > msgid=<7d53-5ca7aa80-1-51005a80@31476855>: stored mail into mailbox > 'INBOX' > Apr 05 19:20:46 portal postfix/lmtp[30765]: 6AC3240807: > to=<andre@homebox.space>, orig_to=<andré@homebox.space>, > relay=portal.homebox.space[private/dovecot-lmtp], delay=0.62, > delays=0.59/0.01/0.01/0.01, dsn=2.0.0, status=sent (250 2.0.0 > <andre@homebox.space> WGTdAo6qp1wueAAAeNB+QA Saved) > Apr 05 19:20:46 portal dovecot[12813]: lmtp(30766): Disconnect from > local: Successful quit > Apr 05 19:20:46 portal postfix/qmgr[21470]: 6AC3240807: removed ---------------------------------- And the message source: ---------------------------------- > Return-Path: <an...@rodier.me> > Delivered-To: andre@homebox.space > Received: from portal.homebox.space > by portal (Dovecot) with LMTP id WGTdAo6qp1wueAAAeNB+QA > for <andre@homebox.space>;

I could ask Google to use HomeBox, but I am not sure they would agree ;-) Regarding your issue, there might be many causes. I remember one, with the dovecot, for the Quota plugin that failed to lookup the user, I had to add "quota_status_nouser = DUNNO", so it does not fail when the user is not found (if I understood well). Another note, I am using LDAP lookups, _and_ a specific schema for unicode email addresses. Otherwise, this would not work: root@portal:/etc/postfix# cat ldap-aliases.cf # Basic LDAP settings for postfix server_host = ldap://ldap.homebox.space/ start_tls = yes search_base = dc=homebox,dc=space search_scope = sub # Allow advanced LDAP search with the recipient delimiter query_filter = (|(mail=%s)(intlMailAddr=%s)) result_attribute = mail # Force support for UTF8 version = 3 Thanks to this, ldap lookup is unicode compliant: > root@portal:/etc/postfix# postmap -q andré@homebox.space > ldap:/etc/postfix/ldap-aliases.cf > andre@homebox.space > The LDAP schema for internationalised email addresses: > # The attribute type 'intlMailAddr' is defined for storing SMTPUTF8 > # compliant addresses [RFC6530] > # https://tools.ietf.org/html/draft-stroeder-mailboxrelatedobject-07 > > dn: cn=intlMailAddr,cn=schema,cn=config > objectClass: olcSchemaConfig > cn: intlMailAddr > olcAttributeTypes: ( 1.3.6.1.4.1.5427.1.389.4.18 > NAME 'intlMailAddr' > DESC 'Internationalized Email Address' > EQUALITY caseIgnoreMatch > SUBSTR caseIgnoreSubstringsMatch > SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) > olcObjectClasses: ( 1.3.6.1.4.1.5427.1.389.6.9 > NAME 'mailboxRelatedObject' > DESC 'Associated RFC 5321 mailbox for any entry' > AUXILIARY > MAY ( displayName $ mail $ intlMailAddr ) ) > As I wrote earlier, All the software in the chain should be UTF-8 ready -- André Rodier HomeBox: https://github.com/progmaticltd/homebox
