in Phoca Guestbook -> Options -> General
I set the option "review item" to "yes"
that means: on every new entry the admin (super user) gets an email to manually approve the new entry.
now: if a user makes a new entry -> this entry is saved properly,
but no email is sent out
instead the user sees this error message right after submitting the new guestbook entry:
"Notice
SMTP Error! Data not accepted.SMTP server error: DATA END command failed Detail: pymilter: untrapped exception in pythonfilter SMTP code: 451 Additional SMTP info: 4.3.0"
see as well the screenshot here: -> https://24max.de/temp/smtp_error.png
the E-mail settings in my general joomla options (global configuration) are set correctly and I tested them with the button "send test mail" as well as with some other extensions I have installed -> all extensions work without any problems regarding sending their notification emails -> except Phoca Guestbook
