Right. I filed a bug report at Eudora Web site.

Here it is:
Supports AUTH type CRAM-MD5 on a non-TLS connection: Yes
Supports AUTH type CRAM-MD5 after STARTTLS connection: No
Supports AUTH type CRAM-MD5 over wrapper mode TLS connection: No
It seems, as Giuliano pointed out, that Eudora enters in
pipe mode as soon as a TLS session is opened. I can see that in Eudora log,
since it doesn't wait for any return code from the server. Here is an excerpt
of the Eudora Log file. (The comments are mine).
