How To Disable Bounces And Sender Verify With Exim?
Oct 11, 2007
in the last few months Ive got a blacklist warning from spamcop over my server sending bounces and now I find out one of my ips is listed at [url]for doing sender verify and bounces.
I think both of which are ridiculous to blacklist for and I really think most of the anti-spam blacklist people are nothing more then money making rackets. But I guess it seems reasonable to disable these things as it would save some resources.
Anyway what I need to do I guess is only do bounces for local users and disable sender verify. What is the best way to do this with exim?
Every server I have to change is cpanel. Ive googled on this the last 2 days and cant find much info, Mailservers isnt my strong point for sure. Any advice Id appreciate.
UPDATE I found how to disable callouts [url]
Just trying to figure out how to disable bounces now

We had a non-client (not on our server) that was getting 550 email rejections when he attempted to email us due to having Sender Verify enabled.
In the past I figured Sender Verify was necessary for fighting spam, amongst other things, but have realized that we may be having more rejections than we know because we never hear about them.
Is there a general best practice in terms of enabling Sender Verify or leaving it off? I've never heard about complaints about rejects from legitimate emails senders, so it doesn't seem to be an issue, but then again, you really never know...

I´m seeing that a lot of servers are rejecting my emails showing this error:
451 - could not verify sender (callout)
Reverse DNS is working fine, and I couldnt see any kind of error on dnsstuff.com.
I´m using EXIM/CPANEL. I tried to send from one cpanel server to another cpanel server and I´m still getting error.

In my Exim mail queue, there are around 33,000 messages, all of which appear to be "Mail delivery failed: returning message to sender" messages.
The reason for these bounces is because spam is being continuously sent to non-existent addresses on my domain.

!verify = helo
!verify = reverse_host_lookup
in exim acl and drop message if helo is not passed.
But one issue is this validates for users even having account in the server and trying to send mail using server account to someone else
I want to put validation for only incoming mails "to" this server
What i dont want is to validate the mails that authenticated smtp users send

My mail server receives tons of messages directed towards bogus, non-existant addresses at my domain. When those addresses don't exist, it creates a reply email with the subject "Mail delivery failed: returning message to sender". How do I stop exim from doing this?

So I get this email today from SpamCop complaining about my server sending unsolicited bounce messages.
Well yea... thanks to spammers domain spoofing and sending spam to my server, my server finds that there's no address - so it replies to the spoofed address.
My question is.... what do I do about it? The spamcop site has this to say... Though if I setup the server to do something odd like not sending a bounce because it's "filed internally", how will legit people get the proper bounce response??
Problem: Misdirected bounces
Description: When a mail server accepts a message and later decides that it can't deliver the message, it is required to send back a bounce email to the sender of the original message. These bounce emails are often misdirected.
Solution: Upgrade and/or configure your mail server software so that this situation is never encountered. Configure your software to either reject messages during delivery or accept them permanently. Do not let your software make choices about delivery after it has accepted a message. If you must accept delivery before you know the status of a message, then file it internally - do not send, forward or bounce it outside your organization. The errant message can be placed in a special folder or routed to your postmaster.

please bear w/ me since this is my first time on launching a site online..
My site is being hosted by a free hosting company..
When I tried viewing the source code of my page some of the html tags are not seen like the <html>,<meta>,<head>...
and I can't seem to verify my site on google...
Verification status: NOT VERIFIED
Last attempt Jan 30, 2009: We've detected that your 404 (file not found) error page returns a status of 200 (Success) in the header.
why is this so?
Did the host delete those?
what should i do?

I had a server admin install a new drive in RAID 1 (mirrored drives). I'm not the best linux guy in the world... but is there a way either through linux, WHM/cPanel, etc. to check and verify that the drives are mirroring correctly? I just want to sleep soundly everynight knowing if a drive failed I'd have another drive up and going.

I have a domain: myname.com
whose nameservers have been already update to the new host's nameservers: ns1.myhost.com and ns2.myhost.com
The new NS for the domain was already propagated over 1 day ago.
However, it seems that myname.com is not yet resolving at myhost.
How can I check whether myname.com is on ns1.myhost.com nameservers?
I have yet no shell access, and it is shared hosting.

This is just to recommend verifying your 404 error pages. We have found they have been replaced by junk advertising.

if there was a way of remotely verifying my dedicated server architecture.
The hosting is done through our design company who then use a 3rd party for hosting a number of sites, and as such I don't have direct access to server control panels etc.
Short of just taking their word for the fact that we have the servers we're supposed to, I was wondering if there's any way I can be sure. We're supposed to have dual web servers plus a database server.

What step can i do to possibly minimize DDOS attack?
