Why Mail Server Always Cannot Send And Receive Emails
Jul 17, 2008
My VPS is working perfectly for over one year. However the mail server of my VPS is always not working about 3 - 4 times a week since three weeks ago. I can login the webmail accounts, just cannot receive emails and send emails.
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 just moved from DirectAdmin to Parallels Plesk and already love the interface. Much better than DA in my opinion.
Let's get to the problem:
When I make a new email account I can login to this account on webmail.domain.com (roundcube) and receive and send emails. Now when I want to use this account on Apple Mail i'm not sure which ports I need to use.
For the incoming mail server I use: 143 For the outgoing mail server I use: 587
Now when I look at my mailbox it gives me a warning sign. The outgoing mail server gives a green dot, but the incoming mail server gives me a red dot.
- So sending mails works. - And receiving mails don't work.
I am using IMAP and have enabled the SSL box. I don't know if i need to check this, because i'm not running on an SSL certificate.
Are the ports that i'm using right? And should I enable the SSL checkbox?
In webmail, when a person trys to send an email they get this error:
Message not sent. Server replied: Requested action aborted: error in processing 451 Temporary local problem - please try later
We have tried all the mail processing apps on Webmail (horde/squirrel/roundcube) and all of them seem to do the same thing. We have restart exim and that doesn't do anything either.
I tried searching Google, but I didn't find too much luck there.
I had made the backups of subscription and of whole plesk too and migrate it to other server. It seems all to be fine, but I cannot send or receive emails In Tools & Settings -> Server-Wide Mail Settings - > Mail Queue I see all mails stored there. The IPs was changed yesterday, and now I can see that WHOIS Infos was chanfed too, the domains are online.
On old server I had no problem with sending of emails (post), it is stil on, because I had not by all domains changed the DNS-Records yet.
We have installed the latest version of Plesk on our server. Our web applications work fine. But we can not send or receive emails. Neither the webmail (login failed) nor pop3 / imap and mail forms on web projects.
Ubuntu 7.04 server amd64 (Host OS) VMWare Server Postfix 2.3.8-2
1) On testing sendmail to Internet encounting following problem;
$ telnet localhost 25 Code: Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. ehlo xyg.com It hung here after hitting [Enter]
2) All mails sent on yahoo.com/gmail.com to this server returned saying users NOT found. However the respective users including Maildir have been created. Mails sent to them on Intranet w/o problem.
We have a CentOS6.5 with 11.5 PLESK. There is a domain named domain.com and there is an alias domain on it that named alias.com and all check boxes of it (Mail,Web,Application and ...) are selected. When we send an email from GMAIL to info@domain.com, we receive it successfully, but when we send that email to info@alias.com, it doesn't receive.
