Exim Sender Verify
Oct 30, 2009We 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...
How To Disable Bounces And Sender Verify With Exim?
Oct 11, 2007in 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
Turning Off Execution Of "Mail Delivery Failed: Returning Message To Sender" In Exim

May 4, 2008I have been searching for a solution to a problem that shouldn't exist but it does.
Background:
I have a customer on a UK server who sends emails to 500+ recipients on a monthly basis, and all but 3 emails are delivered....
The 3 that don't go, bounce after 3 days (as per the exim setup)
The 3 recipient domain's that reject don't seem to accept email from UK/European ip's and I have tried to send them emails from 4 different networks and still they bounce.
I have even tried to contact them via gmail, and still not heard back.
Proposed solution:
I want to be able to send email for that 1 domain to a Postfix Relay I have in the US.
Question:
How do I achieve this within Exim (a Cpanel Server).
I have found that so far its to do with the Router Configuration section within the Cpanel Exim setup, but I cannot seem to find an example of what and where i need to change the config...
Can anyone provide an example?
Exim: User Unknown (domain Forward)
Dec 3, 2007One of my clients has 2 accounts:
- foo.com, with a mail account info@foo.com.
- bar.com, with domain forwarding to foo.com.
Sending an email message to info@foo.com works.
Sending an email message to info@bar.com doesn't work. When using the ZoneEdit SMTP test utility I get the following error message:
Code:
> RCPT TO:<info@bar.com>
< 550 5.1.1 User unknown: info@bar.com
I checked "/etc/vdomainaliases/bar.com" and "/etc/localdomains", they are configured properly.
Any suggestions?
Sub Domain On Different Server Exim Unroutable Address - WHM/cPanel
Jul 28, 2009I have two servers running cPanel/WHM, with BIND and Exim. I have my main domain running on one server (gizmo.mywebhost.net) and wish to host a seperate helpdesk on a subdomain support.mydomain.com (on a second server, stripe.mywebhost.net).
The subdomain mail account test@support.mydomain.com works fine with hotmail, i can send and reveive between my stripe.mywebhost.net server and hotmail without any issue.
The problem is when i try and send mails from accounts hosted on gizmo.mywebhost.net, to the subdomain server stripe.mywebhost.net, i get the following unroutable address error fired back by the local exim process:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
test@support.mydomain.com
Unrouteable address
------ This is a copy of the message, including all the headers. ------

Exim - Mail Filter, Blind Copy All Domain Emails
Apr 2, 2007I have Exim install on my server, I have a few filters setup.
I have several domains on the same server.
What I want to be able to do is blind copy all emails SENT and RECEIVED from *@domain1.com delivered to backup@backup.com
Here is my filter that copies all incoming mail, (THIS WORKS 100%)
PHP Code:
if error_message then finish endif
if $header_to: contains "@domain1.com"
then unseen deliver "backup@backup.com" endif
Now this filter does NOT work, I want it to blind copy all emails sent from *@domain1.com
PHP Code:
if $sender_address contains "@domain1.com"
then unseen deliver "backup@backup.com" endif
I have 1 outgoing mail filer working, however it is for a specific email address, here it is....
PHP Code:
if $sender_address is "user1@domain1.com"
then unseen deliver "backup@backup.com" endif

Hostgator Account Verification
Jun 10, 2008I bought a hosting service from hostgator and received an email from them that I need to verify my account by calling them. I called them 7 times and they just kept saying "hello" and said they cannot hear me and hang up whereas I was able to hear them clearly. I have checked my phone by calling some friends in US and they are able to hear me clearly.
When I searched on google, I came to this forum where somebody has made a similar thread and wrote beware of hostgator. I am really confused after reading that thread. He said his website was available for 10 minutes whereas I didn't even receive my account details from them. I mean the server wasn't setup. I received a welcome email that said the server would be setup in 48 hours & within 7-8 hours, i received an email asking me to verify my account.
What should I do now? I don't even know if they have charged my CC as I can't check my CC statement till 20th.
Verification Of What Ports Are Open
Oct 27, 2007I have used a tool called Net Tools to scan ports on my various servers to determine ports are open in the firewall through my host.
For around a decade, this tool has been accurate to determine what ports are open/closed.
I have used this tool to accurately find issues with the firewall with current host (dedicated server). The network admin says that net tools should not be trusted and even though the software claims the ports are open, they are not open.
I explained that less than a month ago, this software reflected that these ports should closed were reflected accurately as closed by scanning the ports.
Partial results:
Code:
Address Scanned: xx.xx.xx.xx
Scan Started at 10/27/2007 2:08:00 PM
Scan Finished at 10/27/2007 2:18:03 PM
Ports Scanned: 1 To 4000
Total Ports Found Open: 3794
Current Ports Found Open:
Port: 00004
Port: 00005
Port: 00009
Port: 00026
Port: 00044
Port: 00076
Port: 00083
Port: 00088
...
What are the ABSOLUTE best tools/ways that I can confirm that the ports are truly not accessible?

View 2 Replies View RelatedLimeStoneNetworks Verification Takes Forever
Oct 28, 2009My company ordered server on 23/10/2009 from LimeStone, and they asked for verification hence i given them all the ID that they need. After that, they told me they couldn't accept AMEX and have to pay through PayPal, i have paid since and NOW again they asked for ID again.
Why i have to verify for second time since i have posted all my ID and utility bill for first time? I don't think i need to give so much verification since PayPal has already verified my account as i owned PayPal Verified Business Account, this kind of "repeating" or double verification never happen when i order from ThePlanet/EV1 where i am looking to migrate to Limestone Networks.
This is very unpleasant experience and I don't want to wait for more than a week to get a server.

Exim - How To Remove Rbl Lists From Exim.conf
May 2, 2007I am having issues in receieving emails. For some reason, the rbl lists I had setup are causing the server to reject emails (retry - timeout). So, I need to take this rbl list completely. How can I do that? exim.conf is locked and using the advanced editor is no fun even though I tried it putting the dnslists without the rbl causing the problem.
