I 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...
Hoping someone can help here. I have a web server running a couple of sites, has been for a couple of years now. With one of the domains, I have an email forwarder setup through cpanel to forward mail sent to a specific address at that domain to my gmail account (it's a "contact us" type address). I don't think the email address is listed on the web anywhere.
Anyway, I am noticing a lot of spam emails being sent to that address, from that same address and they all appear to be relayed through my exim server legitimately. Obviously they aren't (as I am not sending them).
I am only familiar with sendmail, and am unsure about where to look for any possible hacks to my exim server. Can someone point me in the right direction? I want to stop these spam messages being sent, asap.
- 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.
I 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:

Could you guys look and see if what I am seeing is right? They offer Global Crossing and Cogent officially. So if I use GLBX looking glass, I get this.

I have an interesting situation on my CentOS 4 server. I have a number of virtual adapters (e.g. eth0:1, eth0:2 etc), and for some reason all outbound traffic is going through one of these, not eth0. If I go to ipchicken.com, it shows the ipaddress of a virtual adapter, not the normal eth0 adapter.
I have been looking around for information on how to set the default adapter to eth0, but I can't seem to find anything. I can't reboot yet, as it's a production server, so I have to wait for 'scheduled maintenance'. If that's the solution, I can try it, but I am sure there is another underlying issue/routine here.
Is there a way, while live, to set the outbound adapter back to eth0?
Please note, that I have only just realized this has happened. In fact, it has been this way since November. I can tell because server name stamps on Email messages sent from this server indicate a virtual domain at that IP address. I recall I had done some work around that time, which had involved me ifup'ing and ifdown'ing some of these adapters (but not eth0, or the eth0:100 adapter (if I recall correctly) that is now the default).
Also note that I have groups of eth0 adapters, such like: eth0:1 eth0:2 eth0:3 eth0:100 eth0:101 eth0:102
It's the eth0:100 adapter that is now the default.
We have an AWS plesk instance with around 400 domains on. All domains DNS are pointing mail to a different server and almost all domains have a contact form on their website.
the problem is, the contact forms won't work as mail is on a different server. I'm assuming that the local server thinks mail is on the server and thinks it has already been received?
is this because we need to disable incoming mail for all of these domains? if so how would we go about doing this? I tried stopping all courier-imap services but this didn't seem to work.
I am moving into the world of dedicated servers (from VPS). I just got a server from Serveraday.com /OLM.net.
When I was doing bandwidth tests, I found the server's inbound speed was much slower than outbound. I tried downloading a bunch of different provider's 10MB test files from the command line of my server using wget. They were all around 20-30 Kbps.
When I take those same 10MB files and serve them from my dedicated box, the results are much different. My server can push the files out at over 1Mbps.
Why would my server be set up this way, and is this normal behaviour? I sent a ticket to OLM, but their support seems to take a long time. So I figured I would bounce the question off of all you here on WHT
It appears Comcast is now blocking port 25. As a result, I can't sent outbound email via my dedicated server. They had me change to port 587 for my comast email account, but that doesn't solve my not being able to send outbound from my dedicated server.
Is there anythighn I can do (like change the post my mail server uses to 587) so that I can send outbound mail from my server with outlook (over Comcast connection) or am I just stuck now with using web mail?
i have installed a new mail server i.e. SmarterMail, and from past few days i have devoted much time to find "How to create Out Bound rules in Smarter Mail?" but unfortunately i ended up with no solution, hence here i am seeking help from all the member of WHT for my two questions:
1) Can we create an out bound rule in smartermail?
I'm using the free edition of MailEnable and need to configure each post office to copy all incoming and outgoing email to one of the email accounts on the same post office.
Is there a way to configure this ?
I know I can configure mail forwarding on incoming mail per account but need to do it for all acounts (except the audit account).
e.g. anythinghere@dbnetsolutions.co.uk incoming or outgoing would be copied to audit@dbnetsolutions.co.uk
I'm not sure if this is the right place to be posting this, but at our hotel, we have wireless routers (Linksys) that any of our clients can use to connect their laptops to the internet. We have been getting reports from our ISP that spam has been coming from our external IP address, so I wanted to know what people would recommend as ways to combat either our computers or any of our clients' computers from sending out spam. The internet is connected through a firewall/server computer running linux. I thought about blocking port 25, but I'm sure we would have clients complaining about not being able to send any mail.
I tried a little searching both in Google and on here but this is probably going to be a private or member-based thing anyway.
I've gotten a couple comments that some of my outbound personal mail is ending up in spam folders. I think it's almost completely limited to having Outlook (or Express?) as a client... which I assume doesn't even do network-based lookups. Nonetheless I don't seem to be on any blacklists, and running it through my own spamassassin filter comes up basically zero score. But the fact that more than one person has had the problem concerns me greatly. Also, I haven't seen any significant reason why the content itself would trigger anything.
I realize a public spam test service would basically be a "testing ground" for spammers to evade detection, but there's obviously legitimate uses as well... is there such a tool somewhere? Thanks for any advice. Public information sharing is key to a forum, but PMs are welcome in this case.
