I have a customer who is trying to send email to an email direction but it bounces back with an error like this:
SMTP error from remote mail server after RCPT TO:<bancaweb@credicoop.com.ar>:
host sas.credicoop.com.ar [200.47.24.10]: 450 4.7.1 Client host rejected:
cannot find your hostname, [64.76.xxx.xxx]: retry timeout exceeded
I know it has something about a reversal dns but how do i fix it?
Has anyone seen this before?

Giving up on xx.xxx.xx.xx.
We're running a Plesk Server with CentOS
I migrate from plesk 9.5 to another server with plesk 12.0.18, and then outlook and mail default from iphone don't work, but tunderbird and webmail work well.
In outlook when i put the same configuration than tunderbird and i try to send mail out from my domain said this error:
Error del servidor: '554 5.7.1 <244.Red-88-18-221.staticIP.rima-tde.net[88.18.221.244]>: Client host rejected: Access denied
I don't know if outlook is bad configuration but with plesk 9.5 worked well, and now nothing.
I can recive mail but not send.
Clearly a hosting company can choose whether to have a client forum or not, but do you think they should have one?
View 14 Replies View Relatedssh is driving me CRAZY right now... On an almost stock CentOS 5.1 install (inside a Xen VPS, though), I changed sshd to listen on 2222 instead of 22 and restarted sshd.
All of a sudden:
Code:
matt@t60:~$ ssh -p2222 64.191.108.xxx
ssh: connect to host 64.191.108.xxx port 2226: No route to host
I should note that I'm actively logged into that IP in another window, and that it responds to ping. There most certainly is a route. Yes, I've quadruple-checked that I have the right IP. And I use the -p2222 daily to connect to another machine. This is a virgin CentOS install; I just changed the "Port 22" line to "Port 2222" and restarted sshd (/etc/init.d/sshd restart).
I am not behind any sort of firewall, unless CentOS installs one that I don't know about. (I own the physical hardware, not just the virtual machine.)
I figured it had to do with this error in /var/log/secure
Code:
May 31 19:18:39 relay120 sshd[23359]: Server listening on :: port 2222.
May 31 19:18:39 relay120 sshd[23359]: error: Bind to port 2222 on 0.0.0.0 failed
: Address already in use.
So I changed (uncommented) the ListenAddress directive to:
Code:
ListenAddress 64.191.108.xxx
and restarted sshd again.
I checked the page on megaproxy and everything is fine, I checked it at my home, work, my brother checked it out of state.
BUT. At my client's house and also at my client's friend's house.... they are still getting a 403 page.
We moved the site to the new host yesterday around 2:00pm yesterday it is 10:27am And all my stuff seems to be updated...
Is this an ISP issue? is there anyway I can force a domain to clear cache? is this the problem?
the smtp server have ptr/a records setup, smtp auth enabled, isn't on any blacklist and never was. when sending mails to certain recipients mail returns with 554 error stating the ip is blacklisted. the referencing ip is dynamic ip used by sender, not the server itself. i inspected the headers and server ip is listed in one of the from fields, the client ip is listed under another from fields.
how do i prevent this error from happening? i don't want to relay my smtp server which is perfectly fine to isp smtp server. why isn't the receiving smtp checking the last from field which is server's ip but instead bounce the message because the client is on dynamic ip?
if you have any solution, please share, regardless of the mta you're using. i'll make the appropriate changes in my configuration. i'm thinking it's not my fault but receiving smtp fault because i can send using the same configuration to some other recipients who have spamhaus checking enabled and everything works fine because the server checks on the my server ip and not on the client's ip.

We have a dedicated server running WHM/cPanel. Last week this server (which is in a data center, outside our office) started rejecting SMTP connections from computers outside our office, but allowing connections from our office. We do not have a firewall in place. The message returned from Thunderbird when attempting to connect from outside our office via SMTP was a generic "10060" error.
I did notice that if you go into the config on Thunderbird on a computer outside our office and set it to connect using SSL, it then works just fine. I'm finding this baffling and the logs that I see aren't showing any odd activity or providing a reason for the refusal of the connection.
I also don't understand why it accepts connections from our office, as I would have never changed anything to make it accept only from our office, as we connect from home and other locations as well.
I have DenyHosts to ban an IP after 5 failed ssh logins, and send me an e-mail when it happens. Ordinarily I average around 3 banned hosts a week.
I've gotten ten today. Four of them happened with a couple minutes of each other.
I'm just wondering if this is widespread, as if something new was just unleashed? Or is it just dumb (un)luck? I'm not really concerned; every account has a strong password.
I'm merely curious about whether or not other people have seen a surge in brute-force attempts?
(This machine is just hosting a couple of my sites, which get almost no hits... It's not as if people are specifically targeting me. It's just them guessing "alice" and "bob" type usernames.)
Have a new VPS, changed DNS and all is resolving fine. Check MX recods and again all is well. I can SEND email fine, and it is delivered, but ALL email sent to my VPS with LiquidWed is being rejected.
I checked the mail statistics page in WHM and sure enough there are nearly 300 rejected messages including benign stuff like gmail and monster.com (I had to do an arin lookup to see whom the IP's belonged to)
Any suggestions on how I can fix? I searched before starting the thread and found:
[url]
But the OP in that thread said the advice didn't work.
I've had problem with the VPS getting blacklisted alot lately.
Anyway, I think the problems resolved now and we've not been blacklisted for over 2 days, yet there still seems to be alot of e-mail servers rejecting mails from the server due to blacklisting.

Why would the mail from my server be rejected?
I just upgraded my Plesk 11.5 on Plesk version: 12.0.18 Update #9 , and after the upgrade the Postfix stop working. And forwarding, receiving is not working at all and I am getting message bellow.

When sent mail to all @nblobe.com I got smtp 550 rejected
See log below:
Jan 18 10:55:12 server2 postfix/smtpd[3498]: NOQUEUE: reject: RCPT from localhost[::1]: 550 5.1.1 <jcree@nblobe.com>: Recipient address rejected: User unknown in virtual mailbox
table; from=<mail@server2.888.com> to=<jcree@nblobe.com> proto=ESMTP helo=<webmail.server2.888.com>
From webmail.nblobe.com I can send mail but they do not delivered, but I can receive mail...
I just upgraded to 12.x from 11.5, and now the messages to the mailman lists on the server are being rejected for headers being over 32K.
I finally saw this when joining the list myself to see why so many recipient servers are rejecting the mail. I see many instances of these:
Received-Spf: pass (server.mydomain.net: localhost is always allowed.) client-ip=127.0.0.1; envelope-from=thelist-bounces@clientdomain.com; helo=mail.mydomain.net;
and there's one towards the end with:
Domainkey-Signature: a=rsa-sha1; q=dns; c=nofws; s=default; d=clientdomain.com; b=RYN97cdOiqBdkm17GknWv0IMwOmsBHoK+eRaAjYey1vg6+jke2Z35Z1CFBIs/ZvrSslcc1X3kSzu/5SvHzuZVS1nB7zEPDBdr7jZ/Y3ViFccqDWNQbbFjpW9/7tVrFRssMv55gCMNnDwmgqK8WfU1vMkHwfdsuDnIkmB4OtAfqP9w=; h=Received-SPF:Received-SPF:Received-SPF:Received-SPF:Received-SPF:Received-SPF:Received-SPF:Received-SPF:Received-SPF:Received-SPF:
[Code] ....
How do I stop getting all those Received-SPF: headers prepended to the mailman list? It tags on a header that's well over 32K for a message that is less than 1K.
I run a server and have ONLY problems if i am sending mails to domains hosted by google ...

Here a little bit about my configuration:
a) I have set a Reverse DNS (xyz.mydomain1.com) - My hostname!
b) i run 4 domains on this server (mydomain1, mydomain2, mydomain3, mydomain4)
c) my DNS settings are made by myself in my Domain Provider account
d) i also set SPF records and i use Domain Keys
Everything works like a charm but following now the outputs with my problems:
Here is my postconf -n output:
Code:
root@shamu:/etc/postfix# postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases, hash:/var/spool/postfix/plesk/aliases
append_dot_mydomain = no
[Code] ....
Now I sending a email from my domain2.tld and google rejects this email ...
If I setup an pop3 account from my server in Gmail, Gmail returns:
Failed to get the mail.
The server returned the error
"Cannot assign requested address"

I just got my first dedicated server, and Im wondering what SSH Client people are using?
View 14 Replies View RelatedOpened this to help ppl, and to let them know which one is popular and why.
I know some clients and putty is one of them.
Would like to know you guys opinion which one is safe to use. and why.
I thought Putty was the best but after I tried SSH Explorer I discovered there are better SSH apps
So what is the best SSH client?
