Hello whoever you are.
Rest assured, the issue you're seeing is not one related to Hermes or
Eudora per se. Instead, it's a general issue as seen from time to
time by many users of OpenSSL. OpenSSL is the software on your
provider's server that is responsible for the encryption element of a
TLS mail exchange session.
In particular, that error can show up in log entries on the server
side of a TLS connection. What it means is that there was a problem
keeping the encryption stream stable between the two endpoints. This
is normally due to intermittent network problems (perhaps
lost/dropped packs or TCP issues) which affect the message
authentication context (mac) of the TLS session. It can also be
caused by any software or processes that scan TLS sessions such as
anti-virus or organization-wide network security appliances that
attempt to decode TLS sessions in real time.
The problem is likely somewhere in the network layer. You should
definitely run some network integrity checks between you and your provider.
