New smtp.inf.ed.ac.uk certificate

The x509 certificate used to secure communications with smtp.inf.ed.ac.uk changed this morning.

The authenticated SMTP service uses an automatically generated certificated, ultimately signed by the University’s root CA. The service certificates only last a year, and this morning it was automatically replaced with a new certificate.

Certificate:
    Data:
        Version: 3 (0x2)
        Serial Number: 3811 (0xee3)
    Signature Algorithm: sha256WithRSAEncryption
        Issuer: C=GB, ST=Scotland, O=The University of Edinburgh, OU=Informatics, CN=Automated Server Key CA
        Validity
            Not Before: Jun 28 02:49:21 2016 GMT
            Not After : Jun 28 02:49:21 2017 GMT
        Subject: CN=smtp.inf.ed.ac.uk, OU=Informatics, O=The University of Edinburgh, L=Edinburgh, ST=Scotland, C=GB

If you have previously had to accept a warning from your mailer indicating that you trust the smtp.inf.ed.ac.uk certificate, you will probably have to do so again for this updated certificate.

Our apologies for not warning you in advance.
