i remember a similiar scenario where the affected SMTP server was configured to offer obsolete ciphers / hashings / TLS versions while the integrated SSL lib was not able to handle that all anymore. If the connecting server choosed a offered combination not supported by the ssl lib anymore, connection dropped without meaningful log entries on both sides. hth, niels. -- --- Niels Dettenbach Syndicat IT & Internet https://www.syndicat.com PGP: https://syndicat.com/pub_key.asc --- _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
