Resolved Plesk 12.0.18 Postfix error

[BesnierS]

Hi,

I have a problem with postfix since updating plesk 12.0.18.
If I use an email address hosted on my server and I want to send an email from my computer, the postfix smtp connection is not possible.

I applied the following patch to use port 587 but nothing works and even other ports does not work:

/etc/postfix/master.cf

Original Value is like that:

submission inet n – n – - smtpd -o smtpd_enforce_tls=yes -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_sender_restrictions=

Change it as like as this one

submission inet n – n – - smtpd -o smtpd_enforce_tls=yes -o smtpd_tls_security_level=may -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_sender_restrictions=


Do you have any idea? should I apply another particular configuration?

Thanks

Did you enable Port 587 or "Submission" in Plesk?

Plesk -> Tools & Settings -> Mail Server Settings -> Tick - Enable Message Submission (on all ips)

Hope it helps
Kind regards

Oh, ok.
For reference here's my submission directives..

submission inet n - - - - smtpd -o smtpd_enforce_tls=yes -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_sender_restrictions= -o smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination

Maybe it'll help
Kind regards

Hi i've got a similar problem with android clients.
It's seem that Postfix wont accept plain connection, but only tls ones.
I commented those line in /etc/postfix/main.cf :

smtpd_sasl_security_options = noplaintext
smtpd_tls_auth_only = yes
smtpd_tls_security_level = may
smtp_tls_security_level = may

And i've delete those options from the submissions line of /etc/postfix/master.cf

-o smtpd_enforce_tls=yes -o smtpd_tls_security_level=encrypt

"service postfix restart" and now all seems to go ok.

I also tryed to change values from web interface and my modified main.cf remain correct (with my lines commented out) ... BUT ... i think that if i enable / disable submission from web interface i should modify again master.cf.

Hope i helped you.

Thank you Danièle for this information. However I have this problem for systematics for any equipment... It is very strange... I have already deactivated the TLS. Strangely with Postfix no more protocol works (25, 465, 587). I think of starting all over again on the waiter(server) to see if it gets(fits) better....

I commented out those line in /etc/postfix/main.cf :
#smtpd_sasl_security_options = noplaintext
#smtpd_tls_auth_only = yes
#smtpd_tls_security_level = may
#smtp_tls_security_level = may

And i've delete those options from the submissions line of /etc/postfix/master.cf

In my interface for plesk 12, Enable Message Submission is missing. Is there a setting that keeps it from showing up?

Make sure that you have the same screen:

Thanks for your help.
I realize that I don't have Postfix. My current problem is that I created email addresses on my VPS windows with plesk. I can't get the emails to go through outlook 2013 because the smtp port number is set to 25, which is blocked by my ISP. I am merely looking for a way to use port 465 or port 587 for the smtp server and hoped that clicking "Enable Message Submission" would do the trick. I do have an SSL certificate on my domain name, but am a newbie on VPS and plesk. I would use PostFix, if I knew how to activate that. Do you have a link to instructions for that? That would be great!

 

[IgorG]

If you have Plesk for Windows, your mailserver is MailEnable. You can't use Postfix on Plesk for Windows.
You can enable submission port 587 for MailEnable with following instruction - https://kb.plesk.com/en/122214

Thank you so much. It turned out that I had to use port 465, but the link you sent me lead me to the solution! It WORKS!
