This shows that Postfix does not bounce mail. Instead, Postfix requests that the SMTP client come back later. A client that implements SMTP by the rules will do so. > In: DATA > Out: 554 5.5.1 Error: no valid recipients This is harmless, and is to be expected with clients that use RFC 2920 SMTP command pipelining. If the client interprets this as a mail delivery failure, then that client has a broken command pipelining implementation. You can configure Postfix to not offer pipelining support with smtpd_discard_ehlo_keyword_address_maps: http://www.postfix.org/postconf.5.html#smtpd_discard_ehlo_keyword_address_maps > Aug 31 09:09:20 server postfix/smtpd[17106]: warning: dict_ldap_lookup: > Search error -5: Timed out > > Aug 31 09:09:20 server postfix/cleanup[17106]: warning: AEF14688F: > virtual_alias_maps map lookup problem for p...@home.com I'll leave it up to the LDAP experts to figure out what is wrong.
