Sender Verify - changes in recent Release versions?

[mtindor]

I run our server with Callouts disabled but Sender Verify enabled. I recently upgraded to R18404 (i'm usually only a week behind on updates, no more).

We have a customer who runs MS Small Business Server (SBS) and it handles their faxes. Faxes are sent from:

SBSFaxService@THEIRSERVER.LOCAL

It used to be that if I had thier IP addresses whitelisted in the Exim Configuration Editor, our server would continue to accept mail from that FROM address while still rejecting others that fail sender verification (which is fine).

Since the update, no matter if I add the IP address of their server to the Whitelist to skip SMTP checks and Whitelist their IP from any RBL checks, it still rejects on Sender Verify.

Something appears to have changed recently. Can anybody confirm?

There is a great thread on these forums regarding ways to whitelist certain senders. However, the code mentioned in there doesn't even exist in Exim any longer. the code I have in exim.conf looks completely different with regard to sender verification than it does in that thread.

So I ask again - is anybody else familiar with any _very_recent_ changes in the exim.conf code that handles Sender Verification?

Thanks

Mike,

We recently added White Listing for Sender Verify (skips the verify step). Does this work for you? It's in build 18451+

What is the syntax for the file senderverifybypasshosts?
Thank you

You can edit it within WHM

Can someone please explain this... Is it possible now to disable Sender Verify, or how can I whitelist some senders, maybe by from field, or is it possible only bi IP, and how to do that?

Thanks.

You can do this by IP (not by individual email address). Go to WHM -> Server Configuration -> Exim Configuration. Under Access Lists click the Edit button next to Whitelist: Bypass SMTP time sender verifcation checks. You will be brought to a page where you can whitelist IP addresses.

Ok, thanks, I found that. But is this mean that there is no way to disable sender verification? Why?

You can disable Sender Verification completely by going to WHM -> Service Configuration -> Exim Configuration Editor and under Mail uncheck Sender Verification then click save.

That option is not working after upgrade to cPanel 11.16.0-R18546, that option is just ignored, and when disabled all emails are rejected if sender can't be verified.

Does a rebuild of your exim.conf resolve the issue?
