Human Verification Required
Tried sending a message to a couple Yahoo! Groups I'm a member of via Zimbra, but all I keep getting after I send the message off is this
My reaction was one of :eek:
SendMessage request failed: Human Verification required.
Anyhow, I checked to see if my Yahoo! address was indeed a member of those groups & it was.
Any idea what could be causing this? I have no idea what version I have (I can't even find it).
Human Verification Required
I have also got this error once in a while.
Yahoo customer service response is
"You can send the same message to up to
100 people at a time. To prevent spammers from taking advantage of this
option, no more than 50 of those addresses can be within the same
domain. For example, you can't send more than 50 messages at a time to
people who have addresses at yahoo.com or another email provider
To send your message to more than one person, add additional email
addresses in the To, Cc, and/or Bcc fields separated by commas:
firstname.lastname@example.org, email@example.com, etc.
You can also select a list of recipients from your Yahoo! Address Book,
so the email will be sent to all contacts on that list. "Everyone" is a
list that contains everyone in your Address Book. However, if you have
over 100 contacts, using "Everyone" or another list you've created, your
message will not be sent.
If you do not enter valid email addresses, or if you do not use commas
to properly separate the addresses, your message will not be sent.
Instead, you will see the message: "Message not sent. There is a syntax
error in your address field(s)..."
Remember that to send a message, you must always have at least one
address in the 'To' field. Also note that sending junk mail or "spam" is
a violation of the Yahoo! Mail Terms of Service.
If you want to send messages to a large number of recipients, create a
Yahoo! Group and use it to send emails to everyone in that group. Learn

The message disappears gradually but I am not aware and will like to find out as to how long it remains in "blocked (human verification required)" state ?

Texte français plus bas.
I have just seen your post.
I have had this problem also.
This is cause by yahoo asking to manually write letters/numbers (from a picture) into a text box.
I cannot tell what is the exact technical process but it happens sometimes even if I have only a few recipients.
A way I have found to bypass it, is to go to my yahoo account and copy/paste (from zimbra to yahoo account) the message I have already try to send and send it back. You should then see the "Human...." appear, write the letters/numbers from the picture into the textbox and send the email.

J'ai aussi eu ce problème.
C'est causé par le fait que yahoo demande d'inscrire manuellement des lettres/chiffres (provenant d'une image) dans une boîte texte .
Je ne peux pas expliquer le processus technique en tant que tel mais ça m'arrive quelquefois même si je n'ai que quelques destinataires.
Un moyen de contourner ce problème est d'aller directement dans mon compte yahoo, de copier/coller (de zimbra vers yahoo) le message que j'ai déjà essayé d'envoyer et de l'envoyer à nouveau par mon compte yahoo. A ce moment, j'ai le message "Human...." qui apparaît et je peux inscrire les lettres de l'image dans la zone texte et mon courriel part finalement.
Anti spam? SendMessage request failed: Human Verification required.
I have three email accounts set up on my Zimbra desktop. However, ironically, I only get this problem if I use Zimbra to send from my Yahoo account. It happens all the time with one or more recipients.
Some ISP/web/mail services like bethere.co.uk implement anti spam systems to prevent bulk mailers.
Is this a similar problem? Does anyone know if Yahoo prevents email being sent from certain service providers?
