Add TLS certificate for email relaying in lists.alpinelinux.org

Hello,

As subject states, lists.alpinelinux.org doesn’t offer a certificate for using STARTTLS in MTA to MTA communication. This can be checked by:

$ openssl s_client -connect lists.alpinelinux.org:25 -starttls smtp
CONNECTED(00000003)
didn't find starttls in server response, try anyway...
22101338425312:error:1400410B:SSL routines:CONNECT_CR_SRVR_HELLO:wrong version number:/usr/src/lib/libssl/ssl_pkt.c:386:

Under some email servers setups such as mine, email isn’t relayed if the remote doesn’t provides STARTTLS.

Best regards.
