I can send and receive, but no emails arrive, probably because the registrar has a resolve issue?

Why Mail Server Always Cannot Send And Receive Emails
Jul 17, 2008My 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.
View 4 Replies View RelatedMy Mail Server Will Not Receive Or Send Email
Apr 20, 2007Here 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.

Oct 16, 2014I 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?
Plesk 12.x / Linux :: Cannot Send Receive Emails After Migrate
Oct 31, 2014I 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.

One Account On Server Can't Receive Email's But Can Send "Out"
Aug 29, 2007I 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?
Mail Server / Can't Send Or Receive Mail
Jul 20, 2008In 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.

Ping No Buffer Space Available
Dec 19, 2007i have a custom setup, front end, that serves the apache requests, and a remote SQL Server.
the SQL traffic runs on the internal network.
the front end runs freebsd 6.2, and apache 2.2 with php 5.2.5
the sql server runs centos 5.1, and mysql 5.0.45
tonight, i found that my website was not working, i logged in, and i saw that when i tried to ping the internal network, i had that error:
ping No buffer space available
i was trying to ping the sql server, from the front end. the sql server worked fine, i could ping other servers in the internal network, but the front end's internal card allowed no traffic.
I tried restarting the internal network card, state up/down, did not solve the issue.
When To Add More Ram. Swap/Cache/Buffer
May 23, 2007When is a good time to add more ram?
Since I got my server its ran with 1gb ram and has kept a free of at least 400mb since that time.
Now withing a few hours all of it is being kept in buffer/cache as the past week an showing about 15mb free (not counting buffer/cache) and has started in on the disk swap of about 400Kb.
So should I upgrade to 2gb now or wait till it goes deeper into the swap, and if so how far into the swap before you'd upgrade?
