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
