MailScanner does not deliver some mails to all recipients,

[lehels]

Hello,

We are experiencing a problem with MailScanner, it does not deliver some mails to all recipients which are listed in To or CC, or another strange situatiation is that, the mail is delivered only to the address at "CC:", not also to the mail "TO:". The cause would be that the Full Header is not interpreted correctly[?] There is a way to handle this situation?

Thank you.

We have seen headers get messed up if you include a non-alphanumeric character (space, hyphen, dot, anything but a letter or number) in the %org-name% setting in MailScanner configuration.

If that isn't the problem, you'll need to examine the exim log and mailscanner logs carefully to determine what is happening to the other emails. It may be they are being deleted by a user filter, which we see occasionally.

Regards,
Sarah
