Email 550 Error

[Logicman 0]

I've been using Eudora since 1994.

 

Once in a while, this weird error happens.

 

I send mail to a perfectly normal email address like someguy@yahoo.com, press send, Eudora connects to the mail server, tries to send the message, and then pukes with this error message:

 

"Can't send to ". The server gives this reason: '550 email client.'.

 

I've checked everything. I have authentication turned on. In fact, I never quit Eudora at all, and it was sending mail fine last night. I haven't changed any settings either.

 

Anybody else know what could be the problem? Googling isn't helping because most of them think it's because authentication is not turned on. It is.

I turned on detailed logs in Eudora and here's a relevant portion from the logs:

I'm puzzled about the "incorrect authentication data" bit, given that I can download mail just fine with my regular password.

There are a lot of Endora users here,

hopefully one of them will see this and have an idea.

It seems that it's a Eudora problem. I tried setting up an account in Outlook Express and sending the mail and it went through fine. So it's obviously not a problem with the server (which is a relief.)

 

I've posted the question on Qualcomm's forums. Maybe those guys will have a better idea.

Things to check

My server requires authentication

and maybe change outgoing mail port to 26

 

 

 

 

 

----------

ok you are already doing the authentication thing

 

if you find out,

please let us know

it may help others.

Hi all,

 

I've used the same version of Eudora for years.

 

And today, that mysterious 550 message started blocking all of the e-mails I was trying to send.

This often happens when I'm on the road, but rarely at the home computer. * heavy sigh *

 

Eudora Tech Support offers this bit of information

 

http://eudora.com/techsupport/kb/1593hq.html

 

The net result, if changing the outgoing mail port doesn't work, then you might have to use the SMTP server of the ISP into which you are dialing, hardwired, or wireless for sending mail.

 

I changed the SMTP server to that of my cable modem company and my e-mails were then sent.

 

For travelers, make a note of your changes. Cause when on the road, this change will affect your ability to send mail. You may need to change it back to mail.your-tch-website.com, or to another SMPT server that works for you.

 

If you are using the most recent version of Eudora,

you can use the SMPT relay feature for sending mail:

Am hoping this note saves forum members a few hours of homework and frustration.

 

All the best,

And today, that mysterious 550 message started blocking all of the e-mails I was trying to send.

I'm getting this message today, however, I'm trying to send through SquirelMail. This is the actual error message -

 

Requested action not taken: mailbox unavailable Server replied: 550 server27.tchmachines.com www.xxxxxx.cc) [xx.xx.xx.xx] is currently not permitted to relay through this server. Perhaps you have not logged into the pop/imap server in the last 30 minutes or do not have SMTP Authentication turned on in your email client.

 

Is this a setting I have wrong in cPanel, or do I need to open a ticket?

Welcome to the forums t-rowan

 

How are you trying to send email? Webmail? Email client?

How are you trying to send email? Webmail? Email client?

Webmail using SquirelMail, I get the same error in Firefox & IE. I thought it might be due to some type of blocking at work, but I went home at lunch and had the same result.

Please open a ticket with the help desk. They can help you sort it out.
