I don't typically have any trouble with Eudora... it just works. But once in a while the handshake with the server will stop working. I end up having to contact my web hosting provider and we change some settings and get it back on track. But I never understand why the changes were needed. The provider claims nothing has happened at their end.
This has happened again. I can receive but not send emails. I've narrowed it down to not being able to send to outside email addresses. I thought I was seeing something relating to the email account I was sending from, but it turns out to be the same across the accounts. Here is the error message.
"Can't send to ''. The server gives this reason: '550 without authentication.'."
I exchanged a number of messages with support, but I haven't heard back from them since I found it was connected to the destination email address.
This is a bit odd. Could it be that authentication somehow is messed up when sending emails outside your own server?
At one point we had submission port 587 enabled along with SSL, but Eudora says the certificate didn't match the destination host. Even odder is that it says the error is ignored because the certificate is "trusted", but the connection timed out. It presents a dialog asking if the certificate should be trusted in future sessions, but it doesn't matter what I select there, it always fails again.
Is Eudora getting too old to work well in the current environment?
