Send to multiple Address Email - Invalid Email Error

[dan.carvalho]

Hello Guys,

We are having trouble send to multiple address, more than 90, both on SMTP connections and Zimbra Webmail.

When we try to send to more than 90 address, for some reason Zimbra do not send the mensagem because it identify some invalid address, but all address are valid! I test all the address and all are correct, i used this regex: https://regexr.com/5jad5 .

Here is the error mensage:
* I delete private information
* It is Zimbra v9

Code: Select all

method:	[unknown]
msg:	Invalid address: someemail@hotmail.com. com.zimbra.cs.mailbox.MailSender$SafeSendFailedException: MESSAGE_NOT_DELIVERED; chained exception is: com.zimbra.cs.mailclient.smtp.InvalidRecipientException: RCPT failed: Invalid recipient li.rocio@hotmail.com: 450 4.7.1 <senderaddr@prodest.es.gov.br>: Sender address rejected: 0

      version: "9.0.0_GA_3983"
     }
   }
 }

Someone has an idea how to solve this?
I think is some BUG in ZIMBRA.

Hi,

Someone with same problem?

Could anyone with Version Zimbra.9.0.0_GA_3983 test it for me?

Aside from your regex test, have you done any other validation?

Have you tried a single email from the listed sender to the listed receiver?

Invalid recipient li.rocio@hotmail.com: 450 4.7.1 <senderaddr@prodest.es.gov.br>: Sender address rejected: 0

Yes, the erro message said that one specific address in list is invalid, but this specific email is valid and i send to it normally with the same sender address and the specific same receiver.

What is more strange is that if i try to send to same list of address, the erro message points to another receiver email address, and for sure this email address is valid and i can send msg to it.
