Hi,

A problem started to happen after the last Kerio Connect updates, I dont know from what version started, but the problem happen when any user activate the Out of Office automatic reply.

The messages stop in message queue with this error:

Result: delayed, Status: 4.1.1 450 4.7.1 <emailtal<_at_>tal.com.br>: Recipient address rejected: You are send e-mails with an empty from: or an empty return-path

I tried to find where to set the return-path to Out of Office msgs but I dont find, we use Kerio connect since version 6.x and this never happen.

I will be very glad if you guys could give me some tips.

Thanks in advance,

Roger

This has already been discussed here:

It is quite normal to have an empty From field in DSNs so I suspect it is rather something on the receivers end. They should not reject empty From fields.

Also, have you copied the error message exactly as you got it?

This is just wrong English, I can't imagine that any professional mail server would send back that message.

Thanks to aswer freakinvibe is like my ISP dont accept this messages without a return-path, I received a call from Kerio support Brasil and the guy said the same.

About the wrong english in error msg, that's right, I copied from log, even I that barely know english found it strange the text, but this is my minor problem now. Smile

Thanks.

For me this was important to know, because when you search for this error message on Google, you don't find any results. So that means your ISP has probably coded the error messages themselves.

Normally, if you search for error messages, you can find out the vendor of the recipient's server (e.g. Exchange, Postfix etc.) as each Mail Server software has its unique standard error messages.

In your case, your ISP (or recipient), has obviously modified the error message.

Have you ever tried to send directly, bypassing your ISP? This might solve the problem.

As freakinvibe says, this is the wrong way (for this scenario's receiver) to cut down on spam. Not only are they attempting to stop rule-breakers by breaking rules themselves, but they are also rejecting it with a soft error (4.x.x). This means the message will live in the sender's outqueue for several days with no chance of ever going trough.

A complete waste of CPU, disk and bandwidth on both ends Sad
