I am having a strange issue with Zimbra Community. Version is: 8.8.10_GA_3801.FOSS.
It was working fine until the point where we decided to install a SMTP relay (smarthost). We followed instructions and it worked, but ultimately we decided to remove it. That's when problems arised with sending email.
Now I can send 4-5 emails randomly, and on the next, I'll get an error that looks like this.
Code: Select all
Message not sent; one or more addresses were not accepted.
Rejected addresses: receiver-name <receiver-name@receiverdomain.com>
method: [unknown]
msg: Invalid address: receiver-name <receiver-name@receiverdomain.com>. com.zimbra.cs.mailbox.MailSender$SafeSendFailedException: MESSAGE_NOT_DELIVERED; chained exception is: com.zimbra.cs.mailclient.smtp.InvalidRecipientException: RCPT failed: Invalid recipient receiver-name@receiverdomain.com: 450 4.7.1 <sender-name@senderdomain.com>: Sender address rejected: Access denied

Any ideas on what could be causing this or what to check?
