It is rather sad that the problem is staring you in the face, and the required configuration was explicitly communicated upthread:o http://archives.neohapsis.com/archives/postfix/2013-12/0785.html Your original message reports problems with delivery to a bellsouth.net recipient via: relay=smtp.att.yahoo.com[98.138.31.74]:587 presumably, you've set "relayhost=[smtp.att.yahoo.com]:587" or some similar setting. Per the Postfix documentation (both TLS_README and SASL_README). The lookup key for both TLS and SASL policy should be verbatim next-hop destination, namely: tls_policy: # Ideally use "secure" after configuring a suitable CAfile. [smtp.att.yahoo.com]:587 encrypt sasl_passwords: [smtp.att.yahoo.com]:587 user:pass The "[", "]" around the relay name in the tls policy and sasl password tables are NOT optional. -- Viktor.
