Unable to send or recieve emails.

Hello to you all,

I have got a problem recieving and sending mails. I did search howtoforge and other sites for a solution, and tried to solve my problem.

My ISP is blocking port 25. So I uncomment submission, put port 587 into my router pointing to my server, put TCP 587 into the firewall of ISPConfig 3 restarted the server as proposed in multiple threads. But without succes.

Doing a portscan port 587 is open, 25 is closed. Telnetting to the port functions, but I am unable to sent and recieve mails. In the mail error log there is the remark: No route to host (port 25). Are there other settings I have to change?

With kind regards,

Ad.

 

I have a same issue with ISP (blocking 25).

How you plan to receive emails (or your ISP blocked only sending)? In my case sending possible via ISP's SMTP-server, so receiving (send by others*) is main issue...

 

Thanks Till but editing the master file was the first thing I did.

submission inet n - n - - smtpd
-o smtpd_enforce_tls=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticated,reject

Or is editing only the first line sufficient?
Do I have to put my domain name in main.cf?

 

For sending my e-mail I am now using a relay server. Trying this functiones on gmail.

For another account I have got the message:
Action: failed
Status: 5.6.1
Diagnostic-Code: smtp;554 5.6.1 Body type not supported by Remote Host

I'm still not able to recieve mail. I tried this with and without opening submission.

With kind regards

No I could send mails using SquirrelMail and the mailboxes I created in ISPConfig to gmail but not to another e-mail adress. Then I got a message with the diagnostic code. I solved this problem by putting: smtp_never_send_ehlo=yes in main.cf

If I understand you correctly I am unable to use for instance [email protected] or any other e-mailadress for my site if my ISP does block port 25.

Momentary when I use the same ISP from a different IP-adress, mail to [email protected] is correctly redirected to the adresses I put in customrules. Using another ISP nothing happens. So this is due to blocking port 25?

 

Still strugling with my e-mail. Never give up!

My ISP is offering a way to bypass the closed port 25.

According to them I have this in my MX and A records:

mydomain.com MX 10 smpt.mydomain.com
mydomain.com MX 20 mailrelay.planet.nl
smpt.mydomain.nl A my ip-adress

So I changed the first (existing) MX record from my.domain.com. mail priority 10 to mydomain.com. smpt.mydomain.com. priority 10

and added: my.domain.com. mailrelay.planet.nl. priority 20

and put in as A record smpt.mydomain.com. my ip-adress

Still no succes. Sending no problem receiving non.
Could this work, do I have to change something else in the settings, do I have to use mail instead of smpt?

With kind regards Ad.

 

I think you have forgotten the trailing dots in your records. They should be as follows:

Code:

mydomain.com[COLOR="Red"].[/COLOR] MX 10 smpt.mydomain.com[COLOR="Red"].[/COLOR]
mydomain.com[COLOR="Red"].[/COLOR] MX 20 mailrelay.planet.nl[COLOR="Red"].[/COLOR]
smpt.mydomain.nl[COLOR="Red"].[/COLOR] A my ip-adress

 

Hi Falko,

No I did not forget the trailing dots. I put it in like this:

I solved the problem by forwarding the e-mails at my domain host, but I would like to recieve the mails in squirrelmail on my server.

 

Is it possible you made a typo somwhere? I see you use smpt.mydomain.com, but shouldn't it be smtp.mydomain.com?

 

Hi Falko,

Was a typo I made that before.

Trying to send a mail got this result:

Is this for sending a mail to a remote server?

What's in your mail log when you try to send a mail?

 

No this was a test if I could recieve a mail directed to my domain, so it was addressed to [email protected].

Ad.

 

Did you check your mail log?

Does the MX record of your domain point to the correct server?

 

You mean the log in ispconfig? mail error or warn log?

These are my records:
A mydomain.com. my ip address
A mail my ip address
A smtp.mydomain.com. my ip address
A www my ip address
MX mydomain.com. smtp.mydomain.com. 10
MX mydomain.com. mailrelay.planet.nl. 20
MX mydomain.com. mail.mydomain.com. 10
NS mydomain.com. dns0.domeinbalie.nl.
NS mydomain.com. dns1.domeinbalie.nl.

Let me know what you need from the logs.

 

Your MX settings seem to be ok.

Take a look at the mail logs in the /var/log/ directory.

 

Hi Falko,

Here is (part) of my log. Momentary I am also unable to send mails, this was first no problem.

Please make sure that your server's network configuration is ok, that you have valid nameservers in /etc/resolv.conf, and that port 25 is not being blocked (e.g. by your ISP).
