535 Incorrect authentication data upon new user registration

[picturechasers]

Hi all,

Had cpg working great in no time, registration used to work well including email confirmation.  After lots of customizations a bit at a time, confirming main functionality after each step, now I try to register a new user, and get this error from http://www.picturechasers.com/Stock_Image_Database/register.php

Error message
"""Ran into problems sending Mail. Response: 535 Incorrect authentication data """

Tried lots, but I am grasping in the dark.  I have re-uploaded an entire archived set of files that I thought worked, though error may have happened previous even to this backup.  I suspect the issue is written in config file or other files written by "Admin Mode", since it did not change when I reuploaded every file I had.

New user registration works smoothly when I turn off email confirmation, so I hope that I have only screwed up the email settings.  Settings in "mailer.inc.php" seem fine and I have confirmed settings in  'smtp_username' & 'smtp_password'.


Thanks for the great work of the team to date, after trying 100+ different systems it Seems Coppermine is closest to my needs, and workable for mods even by me!

Darren,

if email confirmation used to work and has stopped without you changing anything, I guess your webhost has changed some settings for smtp. Try to contact them and ask what means of authentification you need to send emails over smtp on your webserver.

Thanks GauGau

I will ask them if they changed settings.  I DO know that they did a php build to install EXIF software for me.

Is  "mailer.inc.php" only place for mail related settings, or could I have settings elsewhere to check.

Thanks

mailer.inc.php is the only place to look!
