DoCoMo, the biggest cellular phone company in Japan, send messages
signed with S/MIME to users. If we verify a signature of a message
from DoCoMo, the verification process fails and the following warning
message is displayed.
gpgsm: Signature made 2006-12-22 13:47:37 using certificate ID 64C04082
gpgsm: critical certificate extension 188.8.131.52 is not supported
gpgsm: invalid certification chain: Unsupported certificate
I don't know this well, but I found the following in RFC3280:
341 06 3: OBJECT IDENTIFIER subjectAltName (2 5 29 17)
If possible, I would request to support this extension.
