mime_header_checks=pcre:/etc/postfix/body_checks

MIME header checks let you reject mail which contains malicious MIME

content, i.e dangerous attachments such as Windows executables. Create the file

/etc/postfix/body_checks

. The following example rejects all mail that

contains potentially dangerous attachments. In my experience, using this example

would filter out most of viruses delivered by e mail. In any event, a virus scanner

should always be installed.

/^((Content (Disposition: attachment;|Type:).*|\ +)| *)(file)?name\ *=\ *"?.*\.(lnk|asd|hlp|ocx|reg|bat|c[ho]m|cmd|exe|dll|vxd|pif|scr|hta|jse?|sh[mbs]|vb[esx]|ws[fh]|wmf)"?\ *$/

7. Configuring Cyrus IMAP

7.1. Creating the config files

You have to create

/etc/imapd.conf

and

/etc/cyrus.conf

7.1.1.

/etc/services

If you like to use sieve (a mail filtering language), you must change an entry in

/etc/services

. With SuSE 8.0 take especially care about the port for sieve, they

defined the wrong port. Add or change the following lines:

pop3

110/tcp

imap

143/tcp

imaps

993/tcp

pop3s

995/tcp

sieve

2000/tcp
