I think someone has successfully make my server to send out emails. Why i know this?
it's because I saw many return emails saying that the emails sent out to their inbox are consider spam. I mean a lot for instance within 1 second, there are more than 10 mails.
Can someone help explains me how I can find the culprit and fix the problem?
I've been getting a lot of "Undeliverable" emails sent to my email address. On these messages, the spammer is using my email on the "From" part of the email...... So whenever he sends out spam, the person(s) getting spammed think it's from me..... And the thousands of Undeliverable email error messages are also sent to me.
Is there a way to stop this from Happening? ....... Besides changing my email address?
I can not send email from my server ,it shows the below error :
"There was an error sending your message: authentication failure [SMTP: Invalid response code received from server (code: 435, response: Unable to authenticate at present)]"
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?
Here is what happened:
We have been running our web/ftp/application/mail server for about 4 years, and running flawlessly. This week one of the computers in the network was infected with a virus that was sending spam like crazy. We got blacklisted, as per this site mxtoolbox.com. Our domain is affordablerto.net. Since then we have isolated the problem, klilled the virus and are no longer blacklisted. But we are not able to send or receive any emails now. I wrote mxtoolbox and there reply was basicly "We can get you up and running if you pay us". I called our ISP and they stated that the ports(25) are open. When I do an smtp diagnostic from mxtoolbox I get the response that Argument 'Length' must be greater or equal to zero.
When I go to dnsreport and input our mail server (mail.affordablerto.net) I get ERROR:
The parent servers say that the domain mail.affordablerto.net does not have any NS records (although they may have some other information on that zone).
When I put in our mail server under mail test I get this Getting MX record for mail.affordablerto.net (from local DNS server, may be cached)... There is no MX record for mail.affordablerto.net! That's bad. Checking for an A record... Got it!
When I put in our domain I get this...well I can not put a link in yet - the software here says I need to take 5 posts before I can link anything. Go ahead and try it yourself.
I am not sure what most of this information means. I am in contact with our DNS provider and they keep on trying to sell me some solution. So does mxtoolbox.
I don't know what to do.
iam always having problem with Email know i have order a new server i try to use some script like phpbb.vb.ipb and some other script that have options to send email when people register etc...
if i register use hotmail there is no email will come to me in my inbox why ?
but if i send email from my hotmail email to my domian name email i get it
so i make some research on the net i find something maybe this could be the problem but as i am newbie to the server i have no idea how i can fix this problem

set reverse DNS for your IP address and if possible an SPF record for your domain.
as you can see he is asking me to set the dns etc i dont no . is there anything i could do via WHM/CP/SSL"PuTTy" etc
I have two domains that I haven't set email up for yet. One is hosted on a good plan that uses cPanel. The other has some not-so-user-friendly interface.
Either case, I haven't set up email because I don't know what to seperate between truth and fiction. I know of the front end measures of cloaking an email link to your site using hex or some other hack so it doesn't show up to spiders and bots.
I also heard a rumor that using generic "webmaster@" on any domain is a surefire way for these bots to spam through. So is that true? Should I name my link like "thiswebmaster@" instead ? (or to that effect?)
What can I do to prevent too much (relatively speaking I guess) spam coming in?
Just started to have problems sending emails out but no problem receiving.
Seems to be a exim problem.. tried updating it but the problem still exist but everytime I restart exim then it works for a few hours before the problem comes back.
I want to have an email alert everytime someone login into my server using ROOT user.
The server is based on Linux system.
Is there any way to stop spammers from spoofing my address? I've had issues ever since I started this server with getting bounced spam where the "From:" field was (jibberish)@mydomain.com which was annoying but not that constant.
I came online this morning to check my mail and had over 1200 e-mails and all of them have "online@wellsfargo.com" as the "From:" address, but the message-ID has my domain name in it..

There's gotta be some way (make that 1204.. just got 4 more bounces) to block spammers from doing this. Could someone help a newbie out?
Anybody got a good script to check the server load and to send email if it is pretty high? Perl or bash one?
View 4 Replies View RelatedI'm having difficulty sending an email to another email address (with a different domain) which is on the same VPS.The trouble is, on the other domain's VPS control panel, within the DNS settings, the MX records have been pointed externally (to an exchange server). Their email is turned off. But bizarrely, their mailbox is full.
It seems as though Plesk is ignoring the MX records, and sending MY email internally to the OTHER domain's mailbox on the same VPS.How do I get Plesk to send my mail to the correct EXTERNAL MX records?
I own a dedicated server, and I have one person on the server that can send emails, but for some reason cannot receive them.
It's only this one account that's facing this issue, so I'm not sure if it's something on the server or their account?
A email account can send email, but cannot receive email, why? How do I know the answer why?

We are running an application on IIS that sends out 4-500 emails per day via a smarthost, but nearly 11,000 every weekend. None of this is bulk mail...
We need a new smarthost provider ASAP, as our current host is discontinuing this service this week, and we were just notified.

I couldnt send email via my website , and occur error:
Persits.MailSender.4error '800a0015'
Logon failure: unknown user name or bad password. /includes/email_functions.asp, line 349
how to resolve it?
I currently have a vps, just name it myvps.com (not subname.myvps.com).
I wanna send email to somename@myvps.com from php
php with sendmail function always try to send to user 'someone' on this vps that doesn't exist, junk the root user mail with mailer-daemon explaining that no such 'someone' user. I want to route it to another server.
SPF correct
DNS correct
Submitted to sender ID 2 weeks ago
Mail server tested to other mail clients all ok
GMAil header test. SPF pass
DNStools test: reverse dns, all ok
Blacklists checked. Im not on it
I cant find any reason anymore why my mails dont arrive.
way to send up to a few thousand emails per day.
These emails are simply replies to people contacting me first then I reply with ONE message from an autoresponder. No further contact is made unless they write me back again.
This is not really something that would work with aweber, getresponse, or a similar service.
And most email service providers seem to have a limit of 250/messages a day.
I'm guessing I will need a dedicated server for this?
Anything else I need on the dedicated server? I only have a few mailbox accounts I use that I access via outlook.
I have a dedicated server with godaddy and it has squirrel mail/sendmail/dovecot etc installed on it. I am able to log-in to squirrel mail but when I try to send email, it fails. Even it's not able to receive email. I restarted sendmail but it still does not works.
I tried to send email through command line but it does not work either.

I recently moved a site from a hosting company to a VPS. I updated the name servers with the domain name registrar and the transfer went smoothly.
However one thing does have me puzzled. As I understand it (and correct me if I am wrong) my new hosting company are now the authority for my zone and should have a zone file which points my domain name at one of their IP addresses? However my previous host has a webbased email panel - if I log in to it I can still send email (but not recieve). This has confused me as I would have thought that my new ISP would have a zone file with an MX record for my email? How is this possible?
Is anyone aware of any good tools or tips that I can use to monitor use of qmail/sendmail to generate and send email messages from PHP scripts on a web server?
I want to keep a check on sites that are sending email from the site, to make sure they are not being exploited and result in our server getting blacklisted by big service providers. I'd love a tool that would automatically block messages from an account after a certain threshold is hit.
I'm running a Plesk 8.1.1 & 8.2.0 server configuration..
I want to notify my user base of downtime due to site maintenance.
I don't think my host 1AND1 would be too happy if I used their mail servers to send over 50,000 emails.
What do you guys recommend? Sending a few thousand emails a day for a month? Are there any services dedicated to sending emails in bulk?
I just opened my "catch-all" email pop account that sends me everything addressed to my server that doesn't have an assigned email address. I check it every few days.
Over 4,500 undeliverables. Someone is using mydomain as a phony return address in different forms (gleskit@mydomain.com, peterepred@mydomain.com etc.) If I got over 4,500 undeliverables, these lowlife creeps must have sent innumerable thousands or tens of thousands using my domain as a return address.
What really stinks is that I've had a bunch of users complain that they're not getting usual auto-messages from my forum software. Come to find out that my domain is now banned from at least one major ISP, I'm guessing probably more by now.
The website I run depends heavily on VOLUNTARY auto-communications and updates. For example, one mailing list I maintain have over 4,800 members who've signed up for updates. It uses other feeds and email functions as well.
Am I to understand that any jackass spammer can hose a server this way, with no redress on the part of the innocent party? Also, how am I going to get back in the good graces of the ISPs and personal anti-spam programs that have now blacklisted my server for no reason?
Besides contacting all of the larger ones personally, I wouldn't even know where to begin addressing this.
Is it possible that some nasty geek with a spam program can just ruin a server in this fashion?
Just checked the account again.
In the ten minutes it took me to write the above post, I just got 54 more undeliverables.
