[IMPLEMENTED] Need for authenticated SMTP for bubba....

[dsp76]

Hi,
as far as I understand, I have 2 options for sending email from bubba:
1) send from bubba as smtp server
2) send through my ISPs smtp server

Both won't work in many occasions ...

regarding option 1)
- at least the largest german freemailers don't accept emails from smtp servers with dynamic IP adresses (web.de, gmx,de, t-online.de). For an example, click here

regarding option 2)
- ISPs either don't have an SMTP, or don't allow to relay other than the email adress assigned by the ISPs (usually only a few use their emailsystems, as it makes it difficult to switch to another provider)

Either I have missed it, but what would be needed is an SMTP server entry, where I can also can enter my userID and my password. So far I could only find the field for the stmp server without any more details to add.

Could this be done in a next release or would I need to edit files manually? Which ones?

regards
dsp

Its now implemented in the 0.52.1 firmware release Thanks a lot!

Adding authenticated smtp is on our todo. Unfortunately it is a bit down on the list

if you feel adventurous you can however try to do it manually. Note, this is not tested by Excito yet.

First of you need to install the postfix-tls package. After that you need to modify your /etc/postfix/main.cf Add the lines:

Code: Select all

smtp_sasl_auth_enable = yes
smtp_sasl_security_options =
smtp_sasl_password_maps = hash:/etc/postfix/saslpw

Then you have to create the password file, /etc/postfix/saslpw, and add your passwords to that. The format should be:

Code: Select all

smtp.myisp.com myuserid:mypw

Where smtp.myisp.com matches what you have put in the SMTP server field in the web-admin UI.

Not being the adventurous type, I'd like to register my vote for high priority on this feature as a standard feature.

I'd like to second (third?) this request.

I tried to do install the postfix-tls package, but no luck. Of course, I have a rather limited linux skill-set, but still am willing to RTM and google.

I may be in the wrong, but it seems many ISPs are requiring authentication. Also, this (email server...) is one of the key features that differentiated Bubba (at least for me) from a lot of NAS boxes.

Thanks.

Kaveman,

You might not need to install the tls-package. We have reports on it working without that. So try just modify the files as stated above.

(We will try to squeeze this feature in to the next release since it is quite essential.)

Hi,
just want to confirm, that its working on bubba. Postfix-TLS could be installed from the Debian sources, however you also need to install:

apt-get install libsasl2-modules

After all the changes to main.cf and the creation of /etc/postfix/saslpw you need to:

1.) postmap saslpw
2.) /etc/init.d/postfix restart

Now its working fine

I would suggest to start an excito Wiki, similiar to ubuntuusers.de Wiki... too much good information gets spread over many messages in many threads....

[tor]

Hi dsp76,

Regarding the wiki we have thought of that. But since keeping it clean of spam etc we decided not to for the time being. We however strongly encourage anyone to add to our Howto forum

Thanks for the info on setting up psotfix for authenticated SMTP. My ISP uses port 587 for the initial connection.

How do I set this up in postfix? Do I add ':587' to the smtp server entry in the admin email setup, or do I need to add this to one of the postfix config files? If so which one?

Thanks!

Hi

Just FYI and the remote case developers did not know this. it may be a good idea to use the dovecot SASL libs. This means you do not need to add new users via shell but it uses dovecots database. As this requires a recompile of postfix this probably is only useful for new upgrades...

Hi all

Just to say that I too would like to see Authenticated SMTP supported directly in Bubba. It seems increasingly common that ISPs insist on this feature. Also, if you subcribe to non ISP providers (eg 1 & 1) this seems to be a standard requirement.

Hi

found a great link to setup authentication and also use TLS (gmail.com)

http://souptonuts.sourceforge.net/postfix_tutorial.html

Have not yet tried the TLS option, but found it usefull to get the authentication working. The /var/log/mail.log said that my ISP smtp server accepted the message... but it never arrived.

These variations did the trick for me

/etc/postfix/main.cf

Code: Select all

relayhost = [smtp.xmsnet.nl]
smtpd_sasl_auth_enable = no
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtpd_sasl_local_domain = $myhostname
smtp_sasl_security_options = noanonymous
#smtp_sasl_security_options =
smtp_sasl_tls_security_options = noanonymous
smtpd_sasl_application_name = smtpd

/etc/postfix/sasl_passwd

Code: Select all

[smtp.xmsnet.nl]         myname:mypassword

then run postmap and restart postfix

Code: Select all

postmap /etc/postfix/sasl_passwd
/etc/init.d/postfix restart

Hi Eek.

Great piece of info! Can you put a copy in the howto section of this forum as well. I think many users will find this interesting

For your information
Using GMail to send mail works.
i used http://souptonuts.sourceforge.net/postfix_tutorial.html
and upgrade postfix using the etch repository.
works great!
