1SSL encryption for remote servers with Websieve
2Method 1
3
4You can turn on SSL connections by setting the variables $useimapSSS=1 and $usesieveSSL=1 in websieve.conf.  Also ensure you set the correct SSL'ized ports for $imapport and $sieveports.  You may instead if you have more then one server enter the correct settings in hash %server_hosts in websieve.conf.
5This method uses the SSL option in the IMAP::Admin and IMAP::Sieve perl modules.
6You must also have Openssl, Net_SSLeay, and IO::Socket::SSL installed on your system.  See the IMAP::Admin SSL section for more info.

9Method 2

11This is an example setup on using stunnel to encrypt websieve connections
12to remote imap/sieve servers using an ssl session.
13
14
15Imap server
16
17stunnel -d imaps -r localhost:imap
18stunnel -d sieves -r localhost:sieve
19
20Websieve client
21
22stunnel -c -d localimapport -r imapserver:imaps
23stunnel -c -d localsieveport -r imapserver:sieves
24
25Where "sieves" is a tcp port of your choice since there is no standard SSL'ized
26sieve port as far as I know. Just make sure it does'nt conflict with an existing port.
27
28You also have to make sure to point websieve.conf $sieveport->localsieveport and
29$imapport->localimapport.  Those 2 ports are also arbitrary ports on the local machine of your choosing.  Again make sure they don't conflict to anything else and also restrict them (tcp wrappers - host.deny, hosts.allow) to access from the localhost only.
