sendmail syntax error

[gefei_1]

I find syntax error when execute "sendmail -v aa@xxx.com". The error output is "Syntax error in mailbox address c.u?aa@xxx.com (non-printable character). Does it some syntax error in sendmail.cf file? How can I solve it?

Best Regards,

Do you see non-printable chars when you do cat -bv sendmail.cf?
Also cat sendmailc.f | vis

Just to eliminate any easy problems, could you please try.

sendmail -v "aa@xxx.com"

If this does not work it should be down to config problems.
