 |
|
Hi I followed this guide to setup postfix and dovecot
https://forums.gentoo.org/viewtopic-t-1057474.html.
Reciving mail works fine bu sending is not perfect.
I can send mail from my workstation (Gentoo using kmail),
But using my Androis phone, Roudcube or Nextcloud mail does not work.
This is what tho log says when I try to send a mail from one of there clients:
| Quote: | | Dec 20 20:15:46 fserver postfix/smtp[1195]: 9D3995A700: to=<myaddress@gmail.com>, relay=gmail-smtp-in.l.google.com[64.233.162.27]:25, delay=0.37, delays=0.07/0.01/0.28/0.01, dsn=5.0.0, status=bounced (host gmail-smtp-in.l.google.com[64.233.162.27] said: 550 Relay not permitted (in reply to RCPT TO command) |
This email is sendt to me from my mailserver:
| Code: | This is the mail system at host mail.mydomain.com.
I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can
delete your own text from the attached returned message.
The mail system
<myaddress@gmail.com>: host gmail-smtp-in.l.google.com[64.233.162.27] said: 550
Relay not permitted (in reply to RCPT TO command) |
I'm using the Bluemail Client on my Android Phone, but I also tried Sony's default mail client.
So what is it that makes kmail work and nothing else ?
Let me know if more info is needed. |

| That's the kind of error I'd expect if the client doesn't authenticate. |

KMail on my workstation works fine.
Roundcube who is installed on the same server as postfix/dovecot is not able to send emails.
BlueMail on my Android phone regardless of using IP address or domain address cant send mail ether
BluMail do a check when you configure the server settings and it does not complain that anything is wrong
All clinets gets access to mails just fine so i can read delete move etc.
This is my setting in kmail for sending e-mail:
Outgoing mail server: 192.168.1.101 (Works also when using domain name)
Login: ****@*****.com
Password: **********
Encryption: TLS
Port: 587
Authentication: CRAM-MD5 (PLAIN works fine too)
Bluemail:
SMTPServer: mydomain.com (192.168.1.101 while connected to my WLAN AP does not help)
Security: STARTTLS (Changing to SSL/TLS gives error(3011))
Port: 587
Autentication: Automatic
And username password stuff.
If more configuration or log info is need let me know.

Run through the telnet testing in the source thread if you haven’t already. Check to see what Dovecot and Postfix are logging when it fails.
If you trust the 192.168.1.x network, then set mynetworks appropriately in Postfix and it’ll avoid the need for SASL on that network. By opening up the Postfix restrictions (if only whilst testing) you should be able to isolate the problem area. SASL and TLS are the likely bits if Dovecot SASL is fully working.
You might want to remove your domain name from those config files. |

Tried out using telnet and this is the resault:
| Code: | Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 mail.mydom.com ESMTP Postfix
ehlo mydom.com
250-mail.mydom.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-DSN
250 SMTPUTF8
221 2.0.0 Bye
|
And:
| Code: | Trying xx.126.xx.21x...
Connected to mydom.com.
Escape character is '^]'.
220 mail.mydom.com ESMTP Postfix
ehlo mydom.com
250-mail.mydom.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-DSN
250 SMTPUTF8
221 2.0.0 Bye |
So the question is why no 250-AUTH line?
I did add 192.168.1.0/24 to mynetworks line in postfix but it did not change anything
| Code: | | mynetworks = 192.168.1.0/24, 127.0.0.0/8 |

Because no TLS.
Postfix comes with a sane default that only allows authentication over secured connection. |

So how do I fix this, whats missing ?
I have followed the howto and I'm out of Ideas.
It's strange that KMail can send email without any problems.
The only differences is that KMail uses TLS and the other clients uses STARTTLS.
STARTTLS is not available in KMail, you have this choices: none,ssl and tsl. |

I don't know kmail, I suppose "tls" means upgrading protocol to encrypted STARTTLS and "ssl" means opening connection that is already encrypted.
Also, you may see SMTP port change when you change the connection type.
You can expect AUTH to work on port 25 - smtp after starttls, and on port 465 -smtps (without starttls, you just open ssl connection up-front), and on port 587 - mail_submission, not sure whether is uses ssl or tls though.
Submission should not allow you send anything at all without providing your credentials, and unauthenticated smtp[s] should only allow local delivery. |
