Danke. Hätte ich erwähnen sollen. Das Throtteling für Port 25 hat der Support deaktiviert und auch, wenn ich zu Port 587 wechsel, erhalte ich diesen Fehler.

Meine main.cf (alles default bist auf):
# Amazon SES Configuration
relayhost = [email-smtp.eu-west-1.amazonaws.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_use_tls = yes
smtp_tls_security_level = encrypt
smtp_tls_note_starttls_offer = yes
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
smtp_tls_loglevel = 1
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

smtpd_relay_restrictions = 
 permit_mynetworks, 
 permit_sasl_authenticated, 
 reject_unauth_destination,
 permit
