Change my domain to avoid being blacklisted

[CarlosBurgos]

Hello, I have a problem with my Plesk server.

I have recently upgraded to Parallels version 11.x and the name of my mail server has changed localhost.localdomain, so I have been introduced in Spamhaus blacklists and CBL.

Could you please tell me how I can edit the name of my machine for my e-mail reach the target?

Thank you so much.

In Plesk go to

Tools & Settings -> General Settings -> Server Settings

Enjoy

Thank you, but the problem persist.

The server name is correct, however, mail servers still read localhost.localdomain from my server and introduced me blacklists.

I've read this link: http://www.unadecodigo.com/2007/05/...main-del-servidor-pop3-courier-imap-en-plesk/

How can I change server name for mail?

Could be that file the problem because mail servers read localhost.localdomain in my server?

If you are blacklisted it will be the SMTP server, with Plesk either Qmail or Postfix.
I've had this where you change the name in Plesk and it doesn't update server wide until after a restart.
Anyway, to do it manually (Ubuntu)...

Postfix:
Edit /etc/postfix/main.cf

look for

myhostname = localhost.localdomain

and change it to.

myhostname = mail.yourdomain.tld

You'll probably need to update the

mydestination =

to

mydestination = mail.youdomain.tld, localhost, localhost.localdomain

And reload postfix.

I haven't used Qmail for a long time, so can't remember.

EDIT: Qmail /var/qmail/controls/me

Have you already checked the Server & Setting options for changing the hostname?

 

[CarlosBurgos]

This is the /etc/postfix/main.cf code that refers to myhostname:

# INTERNET HOST AND DOMAIN NAMES
#
# The myhostname parameter specifies the internet hostname of this
# mail system. The default is to use the fully-qualified domain name
# from gethostname(). $myhostname is used as a default value for many
# other configuration parameters.
#
#myhostname = host.domain.tld
#myhostname = virtual.domain.tld

# The mydomain parameter specifies the local internet domain name.
# The default is to use $myhostname minus the first component.
# $mydomain is used as a default value for many other configuration
# parameters.
#
#mydomain = domain.tld

# SENDING MAIL
#
# The myorigin parameter specifies the domain that locally-posted
# mail appears to come from. The default is to append $myhostname,
# which is fine for small sites.  If you run a domain with multiple
# machines, you should (1) change this to $mydomain and (2) set up
# a domain-wide alias database that aliases each user to
# [email protected].
#
# For the sake of consistency between sender and recipient addresses,
# myorigin also specifies the default domain name that is appended
# to recipient addresses that have no @domain part.
#
#myorigin = $myhostname
#myorigin = $mydomain

Which of the two lines should I edit?

 

[Lloyd_mcse]

Uncomment the myhostname = mail.yourdomain.tld

myhostname = mail.yourdomain.tld

And uncomment

myorigin = $myhostname

That's how mine is.

 

[CarlosBurgos]

I have two lines, which of the two lines must uncomment?

#myhostname = host.domain.tld
#myhostname = virtual.domain.tld

And other question, is it enough to uncomment these lines, or I need to change their content?

 

[Lloyd_mcse]

uncomment either, and add your domain.

myhostname = mail.yourdomain.tld

replacing the "yourdomain.tld" with whatever your domain is. eg: mail.CarlosBurgos.com

myhostname = mail.CarlosBurgos.com

Or just run the command..

postconf -e 'myhostname = mail.CarlosBurgos.com'

 

[CarlosBurgos]

replacing the "yourdomain.tld" with whatever your domain is. eg: mail.CarlosBurgos.com

In my mail client I have configured the account www.carlosburgos.com, not mail.carlosburgos.com, so... should I specify "mail." or "www."?

 

[Lloyd_mcse]

Hi Carlos,
I would use mail and then change the settings in your mail client (Outlook/Thunderbird) if that's what you mean.
Regards

Lloyd

I configure the /etc/postfix/main.cf file with the settings you have told me, but still sending mails from localhost.localdomain.

Then, I send an e-mail from my server to a friend with gmail:

Received: from localhost.localdomain (vrtl10286-b.servidoresdns.net [82,223,124,105].)

Is there some other file involved in sending that I need to edit?

Thanks.

 

[Lloyd_mcse]

Did you restart Postfix?

Ubuntu, run:

service postfix restart

 

[CarlosBurgos]

I've restarted postfix with an error, but I've restarted all Plesk and problem persist.

Finally, I remember your lines:

I haven't used Qmail for a long time, so can't remember.

EDIT: Qmail /var/qmail/controls/me

So, I edited the line of the file in SSH using:

vim /var/qmail/control/me

At the beginning of the file there was a line that said "localhost.localdomain", which is what I edited the name of my server.

Upon restart, no longer appears localhost.localdomain in the emails others recipients received from me (appears my server name), so I guess the problem is solved, is not it?

 

[Lloyd_mcse]

Lovely, glad you got there in the end

 

[CarlosBurgos]

Thank you so much, Lloyd_mcse
