Hi, I am using a letsencrypt tls cert and whenever I receive email, I get the following error. Is this a problem with my certificate? Or with the configuration or something??
postfix/smtpd[526]: warning: TLS library problem: error:060A209F:digital envelope routines:EVP_MD_size:message digest is null:crypto/evp/evp_lib.c:316: I have tried to search google for this error, but I haven't been able to find anything. Can anybody explain it or knows what it means? Chris
