i am confused about setting up mail server.
1.Postfix or sendmail or exim as MTA? which is best?
2. which SMTP/POP3 is best? dovecot or courier or any other
3. or which MTA/POP3 combination is easy and works best?
i am looking for easy installation so that i can use webmail and outlook for emails.
what do you suggest? and of course not commercial ones.
Can i use Qmail or Sendmail or Postfix with WHM other than exim mail SMTP.

I recently moved to virtual dedicated hosting for my website, mainly because I wanted a better mail server to work with to manage a mailing list.
I have a few PHP software scripts for different things: managing affiliates and email marketing.
I want to send mail using both of those via SMTP on my new server. They both have a place to type in the host and username/password.
The problem I am noticing is SASL Authentication. They attempt to connect to the host without any trouble. However, the affiliate software fails SASL Authentication every time I try to send an email or test the email system.
Email marketing software connects when I manually send a campaign. However, users are supposed to immediately receive a confirmation mail upon opting in. In this case, it shows up as an attempt in the mail log, but it fails SASL Authentication. I don't know if it's a problem with the software or not, since it attempts to connect but fails, yet connects successfully in other cases.
My question is this: Is there another way around this? I've contacted my host to double check on the appropriate username/password to pass authentication. I will also be contacting the software developers after I receive an answer.
But if nothing comes of it, is there any way around it? Is there a place where I can have it automatically authenticate if the email is coming from a certain user, or if the attempt is being made from the same server (everything sits on the same server, I use localhost in the software to connect to the mail server). Since I am the only person who has access to the server and uses it, it seems safe to automatically authenticate if the request is being asked by the server itself...
I'm just looking for other alternatives if the software does indeed have a problem and I cannot figure it out.
Keep in mind I am very new to all this server and root access. Just a few days ago I was on a shared hosting plan, so I didn't have any access to anything. With that in mind, I know very little about mail servers, although I've been learning more over the past few days. I only stumbled upon the mail logs on my server recently by browsing files in the control panel (I'm not familiar with SSH, although I do have access to it)
I have a Plesk installation with Commandline access. Also on this server is a Request tracker installation. (The reason for the commandline access) CentOs 6 Server.
All installations are up to date, but this actually broke my installation after the last Plesk Upgrade.
At the last Plesk upgrade, my Request Tracker installation can no longer use sendmail to send email directly from the server.
The errors I am getting are:

My server is using Centos 6.5... I updated from Plesk 11.5 to 12 last week and postfix to 2.8.17.
Since then, all mails sent using the sendmail binary (notifications, mail forwards...) are being rejected with a wrong HELO hostname: localhost.
It seems that sendmail is using locahost as a HELO tag which is not accepted. Here is the following error:

I am having issues in receieving emails. For some reason, the rbl lists I had setup are causing the server to reject emails (retry - timeout). So, I need to take this rbl list completely. How can I do that? exim.conf is locked and using the advanced editor is no fun even though I tried it putting the dnslists without the rbl causing the problem.

My website is running of a windows server, and so doesn't let PHP sendmail work .
I only remembered this recently, and now know why I have been loosing out on clients.
Is there a work around to this? i.e possibly some sort of script that emulates the linux sendmail? Note: I don't have access to the windows server config, it is a shared hosting account.
As I was on windows and hated my hosts spam protection (took almost 3 hours for the spam filter to confirm safety of emails from gmail servers) I moved the email system to an external company, that now manages my pop3/smtp etc. (not sure if this makes any difference - but may as well explain it just incase)
I have installed sendmail program on the server and when I try to send email to any external address, it is trying to connect to localhost. Am I missing anything here?

I want to set up a mail server with e.g three domain names and all three domain names will have few similar email addresses like info, sales, marketing and so on. I know that this can be done by using control panels but I am not big fan of control panels I want to do a pure Linux administration using the command line.
View 6 Replies View RelatedI haven't used Sendmail in a while and would like to clarify a specific setup.
Suppose we have a box hosting a handful of clients, thus it is a Shared setup.
Suppose we have Sendmail sendmail-8.13.1-3.3.el4 on a CentOS 4.7 Final installed with 0 extra configuration other than the default one.
Such setup allows on to relay via the localhost method through php/cgi scripts or even manually through sendmail binary.
Ideal setup would be one where I would have the ability to specify into a file, the usernames allowed to relay email. E.g
if /etc/passwd contains
user1
user2
user3
user3
baduser
user6
spaminguser
than ideally I'd like to pick 'baduser' + 'spaminguser' and disallow them the ability to relay through the localhost.
I should not know anything about their domains or where they are sending.
A general directory setup might be
/home/user1/domain1.com
/home/user1/domain2.com
/home/user1/domain3.com
/home/user2/domain.com
/home/user2/sub.domain.com
etc.
Thus, the server has 0 more than a barebones installation of Sendmail with the following configuration

A spammer has sent a ton of users a phishing email requesting the users password...
I work for a regional ISP, and we deal with alot of elderly people who would probably send him a response with a password... I looked over the mail log and one person did respond back to him...
Basically... I want to do like... a virtusertable entry that forwards any email sent to HIM... to ME...
so basically... his email is for instance: phishingspammer@gmail.com
I want to do something like this in the virtusertable (I understand it probably cannot be done thru the virtusertable):
phishingspammer@gmail.com goodguy@regionalisp.com
This way I can alert the people who DO try to send him emails that the email was stopped and to never respond with a password.
I sent email through php function mail - false.
Open putty ->
php -r 'mail("***@gmail.com","test","jjjjjjjj";'
sh: /usr/sbin/sendmail: No such file or directory
SENDMAIL not installed ?

View 3 Replies View Relatedon a sendmail issue that I'm seeing, to which both my hosts are saying "nothing wrong at this end".
Some background:
A few months back, I moved my XXX.com from SLHost to another host. But I forgot to remove the account in WHM at SLHost until a day or two ago.
Since then, mails generated by the server (eg, from a PHP script, or the cron messages) are not getting to the XXX.com account - they're just sitting in the mail queue. I can use POP3 to send mails from accounts on SLHost to XX.com without any problems.

DNSREPORT.COM WARNINGS:
WARNSOA REFRESH valueWARNING: Your SOA REFRESH interval is : 86400 seconds. This seems high. You should consider decreasing this value to about 3600-7200 seconds (or higher, if using DNS NOTIFY). RFC1912 2.2 recommends a value between 1200 to 43200 seconds (20 minutes to 12 hours, with the longer time periods used for very slow Internet connections), and if you are using DNS NOTIFY the refresh value is not as important (RIPE recommend 86400 seconds if using DNS NOTIFY). This value determines how often secondary/slave nameservers check with the master for updates. A value that is too high will cause DNS changes to be in limbo for a long time.

RFC1912 suggests 2-4 weeks. This is how long a secondary/slave nameserver will wait before considering its DNS data stale if it can't reach the primary nameserver.

RFC1912 2.1 says you should have a reverse DNS for all your mail servers. It is strongly urged that you have them, as many mailservers will not accept mail from mailservers with no reverse DNS entry. You can double-check using the 'Reverse DNS Lookup' tool at the DNSstuff site if you recently changed your reverse DNS entry (it contacts your servers in real time; the reverse DNS lookups in the DNS report use our local caching DNS server).

If your mailserver sends out E-mail using this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam software. This is also a technical violation of RFC821 4.3 (and RFC2821 4.3.1).
