RFC 8461, "SMTP MTA Strict Transport Security (MTA-STS)", September 2018

Section 3.2 says:

sts-policy-max-age-value = 1*10(DIGIT)

It should say:

sts-policy-max-age-value = 1*8(DIGIT)

Notes:

As described under 3.2 at point "max_age", the maximum lifetime of a policy may only be 31557600 seconds. Therefore 8 digits in the ABNF for "sts-policy-max-age-value" would be sufficient.

On the other hand, if values larger than 31557600 seconds are allowed, the text under "max_age" should be adjusted.
