Syntax Error Fixup
The MTA normally attempts to fix common syntax errors when it processes message header fields. It is sometimes useful to disable this behavior so certain syntax errors aren&#x27;t corrected. The  source channel keyword enables this behavior. is the default.

At present disabling syntax error fixup is limited to header fields containing addresses and message ids. This may be extended to include other types of fields in the future.

Important note: Many other agents depend on syntax error fixup by the MTA. Disabling it may fix some problem but cause unexpected side effects. It is always preferable to fix whatever is generating the syntax errors so it doesn&#x27;t do that any more.
