Message text

Quoting needed for char %s

Description

RFC 2822 defines very strictly character set allowed to be used in headers unquoted. Some clients do not use quoting in all situations where needed.

Header text will be reported in following SMTB-789 log messages.

This error can occur while reading an incoming mail, or during initial configuration check (e.g. of MODIFY-HEADER items). In the former case, mail is rejected (E-level message) or passed (W-level message) according to the configuration settings (CORRECT-QUOTING directive in MAIL-FILTER section). In the latter case, this error is treated as warning only - check whether this RFC violation is really needed.
