Do you disbelive you own findings? You report that the same certificate is accepted when the MUA is configured to connect to the subject commonName and rejected when the client is configured to connect to a DNS subjectAltName. What conclusion do you draw about the MUA? > As i planned to operate that way, buying cheap ssl certs for > multiple domains/subdomains i would like to be sure before discarding that > procedure. The subject DN needs to be compatible with the needs of clients that don't support subjectAltNames. This may limit your freedom to choose server names and will constrain the set of usable certificates. Clients that support subjectAltNames can be handled by adding appropriate DNS subjectAltNames. -- Viktor.
