Re: [EP-tech] eprints integration with office365 SMTP

Hi Francis,

 all this means that you can not send email (relay denied) to the domain "iisc.ac.in" using 127.0.0.1 and port 25 with clear protocol (without ssl) and without authentication.
You should check the postfix configuration with your system administrator and evaluate at least what you have in the "smtpd_relay_restrictions" and "mynetworks" variables.
To quickly see the postfix configuration use the "postconf" command

The "mail" program directly uses the "sendmail" program which is part of "postfix" so I'm not sure how it behaves.

Good luck
  Enio

Hi Enio, Thanks for your reply.

The output of execution of the script, smtp_send_test_email.pl, is:

-bash-4.2$ perl smtp_test_send_email.pl

I tried assigning eprints@eprints.iisc.ac.in and eprints@iisc.ac.in to
the $from variable. For both the values, Relay access is denied.

So, what does 'Relay access denied' indicate? As I have been
mentioning, using 'mail' command, I'm able to send out mails from
eprints.iisc.ac.in.

Thanks and regards, Francis

Change the variable $from and $to and run the test.

If the mail arrives then the problem is in the configuration of your
"eprint".

Hi Enio, Thanks for the reply. Yes port 25 is open

   netstat -napt | grep 127.0.0.1:25 doesn't find the pattern, but
netstat -napt | grep 0.0.0.0:25 returns the following output:

tcp        0      0 0.0.0.0:25              0.0.0.0:*

Also, I'm able to telnet to port 25:

telnet 127.0.0.1 25
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

Hi Francis,

the problem seem to be in "Failed to create SMTP connection to localhost" found in https://github.com/eprints/eprints/blob/2d42b2be54004bf3db6881a6d893d39c7a7f909f/perl_lib/EPrints/Email.pm#L169

EPrint use "my $smtp = Net::SMTP->new( $smtphost );" on line 166

and defaut to port 25 on "$smtphost" (localhost).

Is your postfix active on this port?

netstat -napt | grep 127.0.0.1:25

Hi, Thomas, thank very much for the kind reply.

Yes, I have tried both  'smtp_server' => 'localhost' and 'smtp_server'

Hi Francis,

'smtp_server' => 'smtp.office365.com'

have you tried
'smtp_server' => 'localhost'
instead?

Are there any helpful messages in /var/log/exim4/mainlog?
