Hello, Please check if the following helps. We received the info (I believe it's taken from Eudora support pages) from our CGPro customer who had problems with Eudora authenticating to CGPro. The FixBustedSMTPAuth.hqx file should be available from the Eudora web site.
======== Summary: 553 - Unable to Send Mail / SMTP Auth (Mac) Book: Support Solutions Page: 2354HQ ISSUE: I can't send mail. The error message always begins with 553, followed by text similar to "Due to an error, you are unable to send mail". SOLUTION: A sending error message that begins with 553 usually involves authentication being required. If you are having trouble sending mail due to an error regarding authentication being required, it is possible that your ISP is now requiring you to authenticate before you can send email. Authentication can be done in a variety of ways, the most common being "login" and "plain". Unfortunately, many mail servers advertise that they support the "plain" version, but do not do so correctly. This plugin will solve this problem by causing Mac Eudora to use the "login" variety, even when the server advertises that it supports plain. To install this plugin, do the following: First, in Eudora, select Special->Settings, then scroll to the "Sending Mail" panel and make sure that "Allow Authorization" is checked. If this alone does not fix the problem, do the following: 1. Download the file FixBustedSMTPAuth.hqx. It is a Binhexed Stuffit archive. 2. Unstuff the file with Stuffit Expander or similar utility. The resulting file will be called FixBustedSMTPAuth. 3. Move the UNSTUFFED file into your "Eudora Stuff" folder. This folder should be inside your Eudora Application folder (the folder where your Eudora application is installed). 4. Quit and restart Eudora. 5. In Eudora, select Special->Settings, then scroll to the "Sending Mail" panel and make sure that "Allow Authorization" is checked. -- Best regards, Dmitry Akindinov. ======================================================================= When answering to letters sent to you by the tech.support staff, make sure the original message you have received is included into your reply. ----- Original Message ----- From: "Christian F Buser" <[EMAIL PROTECTED]> To: "SIMS Discussions" <[EMAIL PROTECTED]> Sent: Monday, February 25, 2002 20:08 Subject: SMTP authentication > Using SIMS 1.8b9d9, I cannot get SMTP auth to work. > > In the SIMS SMTP settings I have: > (X) Advertise AUTH Capability > (X) Allow ETRN for clients only > For 45 seconds, authenticated IPs are treated as clients > (X) Relay for clients only > (X) Verify return paths > > However, with Eudora 4.3.3 and 5.x (both paid, on MacOS) I cannot make it work.
