SMTD-742 — Incorrect character found in mail body
The proxy received mail message with an incorrect character. The log message contains the character (in text and hexadecimal form), mail part description and index.
Proxy behavior depends on configuration and error severity:
Non US-ASCII char occurs in mail or MIME header. This is not allowed and mail is rejected (E-level message) or passed thru as incorrect (W-level message) depending on the MAIL-FILTER.ACCEPT_8BIT_HEADER configuration directive. Also, the SMTB-789 error message is logged. Be careful and use this directive only if you are sure that all MTA next to Kernun are prepared for such mails.
Non US-ASCII char occurs in 7-bit mail body or MIME part. If enabled by the MAIL-FILTER.CORRECT_8BIT_BODY configuration directive, the mail is corrected by adding the 8-bit declaration (W-level message). Otherwise, the mail is rejected (E-level message).
Illegal character (e.g. NUL or bare CR) occurs. If enabled by the MAIL-FILTER.CORRECT_BAD_CHAR configuration directive, the mail is corrected by using of proper encoding (W-level message). Otherwise, the mail is rejected (E-level message).
