I'm using Eudora, how do I fix the SMTP 553 error?
Solution
The different ways to check your identity (authentication) are CRAM-MD5, LOGIN or PLAIN.
If you
check
the box in
Tools - Options - Sending Mail - Allow
authentication
Eudora will try to use CRAM-MD5 first and later LOGIN and PLAIN to send your emails to the SMTP server safely.
Apparently either this switching from one checking method to the other does not work in all cases.
If you go into the settings file of Eudora (ie,
C:\Program Files\Qualcomm\Eudora
), you can look for your personality profile (ie.,
deudora.ini
) settings and add a single line (using a test editor), which disables CRAM-MD5:
SMTPAuthBanished=CRAM-MD5
Example
deudora.ini file:
------------------------------------------------------------
[Settings]
NC=1
Code=NC
UseAppData=1
SMTPAuthBanished=CRAM-MD5
[Mappings]
out=txt,ttxt,TEXT,text,plain
both=doc,MSWD,,application,msword
------------------------------------------------------------
Save the file and restart Eudora.
Most probably your strange 553 error from the SMTP server will be solved.
