550 Sender verify failed

[gnuarm.del...@gmail.com]

I have a persona which is used for sending email from a particular address. My understanding is the login is done with the data in the User Name field. I made a change to the Email Address field to adjust the name in the return address and now I get a 550 error on trying to send the email. When I undo that change it works ok again.

There is no account with the email address, that's just for the return address. So what is going on that changing it alters the authentication? I did the same thing to another persona a couple of days ago and it worked fine.

I need to make notes here when I fix problems so I can find the solution when I have the same problem again.

I lost a machine, but have the hard drive. I've been setting up two other machines with my data, but one of those crapped out too, so another setup and I'm getting the error on sending email, "550 SMTP AUTH is required for message submission on port 587". I'm sure my service provider indicated I needed to use that port to send email. If I turn off the use of port 587 I get an error saying "550 relay through this server without authentication".

Anyone up to speed on this?

Finally got to the root cause. There is something about copying the Eudora installation between two computers that makes the password not work. For some bizarre reason it manifests as the above error rather than saying the password was not accepted. I don't recall what parameter I changed in the setup that triggered a prompt for a new password, but that fixed it. In my other email personalities I simply used the menu to force a prompt for a new password and that fixed those.

I'm still having a problem with reading email, but that's likely because the advice from my ISP screwed it up. If had had written down the values changed I could get it all working again. lol

Yup! I removed the port 995 they told me to use for POP3 and let it default to 110 and it's reading again. However, now the send doesn't verify once more... oh, bother! They guy "helping" me wrote back asking if I actually used the settings he provided. That's just the sort of help I need.

I've got it now.

If you choose non-SSL/TLS option, then you can use the settings given below:

Incoming Server: mail.arius.com
IMAP Port: 143
POP3 Port: 110
Outgoing Server: mail.arius.com
SMTP Port: 587

The error message was "550 SMTP AUTH is required for message submission on port 587" which is actually a result of a problem with the password. Forcing the password to be forgotten fixes this error. There must be something about moving the files between machines that mucks up the remembered passwords. Eudora doesn't seem to know the passwords are not correct or missing and proceeds without informing you. The error presented is rather oblique, sending me on a days long hunt to find my very own posts about it in the ever winnowing support for Eudora. Reminds me of the movie Memento.

I also discovered that a new laptop does not have an Ethernet jack... Just two USB-A, one USB-C and an HDMI, not even an SD card slot! Man, they were really counting the pennies on this one.
