Fully understand your recommendations. The SMTP service, where the postfix SMTP client is supposed to authenticate using SASL, awaits in the „authentication identity“ of the „PLAIN SASL mechanism message“ (RFC 4616) additional „IP-Address:Port“ information to address a system behind the SMTP-Service and further infos, all delimited from each other by „#“. The RFC 4616 itself allows all ASCII characters and further UTF-8 encoded Unicode chars except NUL for all message parts. So in the end from postfix side only „:“ is impossible to use in the „authentication identity“, other „special“ characters are „allowed“.
