Jake,
I just got my first one of these also. I added the mx address from which it originated and set the sender_nocheck="1".
I will know tomorrow if that took care of it.

Hello list,

I have a client who is trying to send email using his blackberry to addresses on the qmailtoaster and is getting the following ‘chkuser’ rejection:

<<

From: "Mail Delivery System" <[email protected]>

To: <SRS0=/[email protected]>

Subject: Delivery Status Notification (Failure)

The following message to <[email protected] <mailto:[email protected]>> was undeliverable.

The reason for the problem:

5.1.0 - Unknown address error 571-'sorry, sender address has invalid format (#5.7.1 - chkuser)'

Is the following the solution:

And, how would a person accomplish this, by editing one of the ‘c’ files?

I find it interesting that this doesn’t always happen when a client sends from a blackberry.

Thank you!

Eric


Easiest way to allow this is to add this to your :allow entry in tcp.smtp:
SENDER_NOCHECK="1"

As to why it only happens sometimes, read one of the posts I've made on this over the last couple years. I believe I explained it in depth a year or so ago.
