Attachments

[Colin Jack]

Hmmm ... it looks like MailScanner is refusing the attachments because
the .zip file contains unacceptable files ... e.g. .exe and .chm

This seems a little over the zealous. We usually suggest to clients
mailing .exe files (install files for example) to .zip them up to get
through filters!!

What is the best way to deal with this? Can I tell MailScanner not to
look inside .zip files

Thanks
