Bug description:
sSMTP is limited to using TLSv1.0 and the "old" ciphers that come with
it. Here's a packet capture when ssmtp connects to
smtp.sdeziel.info:587 that offers TLSv1.0 and higher:
$ tshark -ta -Vr submission.pcap | sed -n '/^Frame 14:/,/^Frame 15:/ p' |
grep -E '^[[:space:]]+(Version|Cipher|Handshake Protocol)'
Version: TLS 1.0 (0x0301)
Handshake Protocol: Client Hello
Version: TLS 1.0 (0x0301)
Cipher Suites Length: 30
Cipher Suites (15 suites)
Cipher Suite: TLS_RSA_WITH_AES_128_CBC_SHA (0x002f)
Cipher Suite: TLS_RSA_WITH_AES_256_CBC_SHA (0x0035)
Cipher Suite: TLS_RSA_WITH_CAMELLIA_128_CBC_SHA (0x0041)
Cipher Suite: TLS_RSA_WITH_CAMELLIA_256_CBC_SHA (0x0084)
Cipher Suite: TLS_RSA_WITH_3DES_EDE_CBC_SHA (0x000a)
Cipher Suite: TLS_DHE_RSA_WITH_AES_128_CBC_SHA (0x0033)
Cipher Suite: TLS_DHE_RSA_WITH_AES_256_CBC_SHA (0x0039)
Cipher Suite: TLS_DHE_RSA_WITH_CAMELLIA_128_CBC_SHA (0x0045)

Cipher Suite: TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA (0x0016)
Cipher Suite: TLS_DHE_DSS_WITH_AES_128_CBC_SHA (0x0032)
Cipher Suite: TLS_DHE_DSS_WITH_AES_256_CBC_SHA (0x0038)
Cipher Suite: TLS_DHE_DSS_WITH_CAMELLIA_128_CBC_SHA (0x0044)
Cipher Suite: TLS_DHE_DSS_WITH_CAMELLIA_256_CBC_SHA (0x0087)
Cipher Suite: TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA (0x0013)
I would expect ssmtp to use TLSv1.2 and a recent cipher like the
openssl s_client is able to do:
$ echo | openssl s_client -connect smtp.sdeziel.info:587 -starttls smtp
2>/dev/null | grep -E '^[[:space:]]+(Protocol|Cipher)'
Protocol : TLSv1.2
Cipher : ECDHE-RSA-AES128-GCM-SHA256
