Redirecting FROM external address TO external address through SES

Post by novelgrind »

Hi -

We're having a problem with redirecting email *FROM* an external address *TO* an external email addresses through MailEnable while using Amazon SES for SMTP.

I've searched the docs, web searched, searched this forum, and can't find anyone talking about this problem.

Here's the situation:

We create a mailbox for "" through MailEnable Management.

Through Mailbox > properties > Redirection, we redirect this to:

Now, if I send an email from a mailbox on to joe1, both joe2 and joe3 get it. So far, so good.

But if we send an email from a mailbox outside of our domain, joe2 gets it, but joe3 doesn't.

For example, let's say someone on gmail sends to Joe2 gets it. Joe3 doesn't.

In MailEnable admin, if I go to Servers > localhost > Services and Connectors > Postoffice > Properties, there's a setting for "Redirection Handling."

If I set that to either "Normal redirection" or "Redirect as an attachment" joe2@ourdomain gets the message, but joe3@gmail doesn't.

If I set it to "Remail from mailbox address", joe3 still doesn't get it, but we get this bounce back about it:

MailEnable: Message could not be delivered to some recipients.
The following recipient(s) could not be reached:

Recipient: []
Reason: 554 Message rejected: Email address is not verified. The following identities failed the check in region US-WEST-2: Joe Sender <>
It looks like Amazon SES wants the original sender to be verified - which we can't do, because we don't know in advance who the senders will be or if we can get them to verify.

Anyone have any suggestions?

Thanks in advance.

Generally you cannot do normal redirection since it preserves the original SMTP envelope sender, so you'd need to have your server in the senders SPF record. If you are redirecting from Gmail you would need to either remail from mailbox or as attachment. Since both of these are failing, but sending an email with redirection is ok, make sure that your has both SPF and DKIM configured. This should then be able to pass to Gmail. Also make sure you are using version 10.46 or later of MailEnable since there was some redirection changes with DKIM.
