Note that the "lost connection to localhost" is an issue when sending email, while TLS on port 587 is inbound email, only tangentially related to the reported problem. STARTTLS on ports 25 and 587 is working just fine for your domain. > smtp-amavis unix - - n - 2 smtp > -o smtp_data_done_timeout=1200 > -o smtp_send_xforward_command=yes > -o disable_dns_lookups=yes Here you mmay want to also add: -o smtp_tls_security_level=none > postconf -n > content_filter = smtp-amavis:[127.0.0.1]:10024 Your amavis content filter is on localhost, and may not handle STARTTLS correctly. > smtp_tls_security_level = may But you try TLS if offered. You can also disable TLS in the port 10025 post-filter service: > 127.0.0.1:10025 inet n - n - - smtpd > -o content_filter= > -o local_recipient_maps= > -o relay_recipient_maps= > -o smtpd_restriction_classes= > -o smtpd_client_restrictions= > -o smtpd_helo_restrictions= > -o smtpd_sender_restrictions= > -o smtpd_recipient_restrictions=permit_mynetworks,reject > -o mynetworks=127.0.0.0/8 > -o strict_rfc821_envelopes=yes > -o smtpd_error_sleep_time=0 > -o smtpd_soft_error_limit=1001 > -o smtpd_hard_error_limit=1000 by adding: -o smtpd_tls_security_level=none There's no need for TLS on the loopback interface except in the unlikely case that you're authenticating to an LMTP server with client certificates, or the loopback SMTP service is actually TCP tunnel to a remote destination. -- Viktor.
