[support] What are the SMTP values for Exim4?

[ghost]

I have this

# Isso can notify you on new comments via SMTP. In the
# email notification, you also can moderate comments. If
# the server connection fails during startup, a null
# mailer is used.
[smtp]

# self-explanatory, optional
username =

# self-explanatory (yes, plain text, create a dedicated
# account for notifications), optional.
password =

# SMTP server
host = localhost

# SMTP port
port = 587
#465

# use a secure connection to the server, possible values: "none", "starttls"
# or "ssl". Python 2.X probably does not validate certificates (needs
# research). But you should use a dedicated email account anyways.
security = none
#starttls
#ssl

# recipient address, e.g. your email address
to = somenxavier@gmail.com

# sender address, e.g. isso@example.tld
#from = isso@somenxavier.xyz

in isso.conf but SMTP sending emails does not work. I use Exim4. What is wrong?

[posativ]

Do you have adjusted your notification configuration? E.g. notify = smtp.

[ghost]

Yes:

$ cat /etc/isso.conf 
# In this section, you configure most comment-related
# options such as database path, session key and hostname.
# Here are the default values for this section:
[general]

# File location to the SQLite3 database, highly recommended
# to change this location to a non-temporary location!
dbpath = /var/lib/isso/comments.db

# URL to your website. When you start Isso, it will probe
# your website with a simple GET / request to see if it can
# reach the webserver. If this fails, Isso may not be able
# check if a web page exists, thus fails to accept new
# comments.
# You can supply more than one host.
host =
  http://somenxavier.xyz/
  https://somenxavier.xyz/
  http://theque.somenxavier.xyz/
  https://theque.somenxavier.xyz/

# Private session key to validate client cookies. If you
# restart the application several times per hour for
# whatever reason, use a fixed key.
#session-key = ... # python: binascii.b2a_hex(os.urandom(24))

# Time range that allows users to edit/remove their own
# comments. See
# https://github.com/posativ/isso/blob/master/docs/CONFIGURATION.rst
# for valid values.
max-age = 15m

# Select notification backend for new comments. Currently, only SMTP is
# available.
# Select notification backend(s) for new comments, separated by comma.
# Available backends:
#
# stdout
#     Log to standard output. Default, if none selected.
# smtp
#     Send notifications via SMTP on new comments with activation (if
#     moderated) and deletion links.
notify = smtp

# Enable moderation queue and handling of comments still
# in moderation queue
[moderation]

# Enable comment moderation queue. This option only affects
# new comments. Comments in modertion queue are not visible
# to other users until you activate them.
enabled = false

# Remove unprocessed comments in moderation queue after
# given time.
purge-after = 30d

# Isso can notify you on new comments via SMTP. In the
# email notification, you also can moderate comments. If
# the server connection fails during startup, a null
# mailer is used.
[smtp]

# self-explanatory, optional
username =

# self-explanatory (yes, plain text, create a dedicated
# account for notifications), optional.
password =

# SMTP server
host = localhost

# SMTP port
port = 587
#465

# use a secure connection to the server, possible values: "none", "starttls"

[guard]

# enable guard, recommended in production. Not useful for
# debugging purposes.
enabled = true

# limit to N new comments per minute.
ratelimit = 2

# direct-reply
direct-reply = 3

mail program in console works: I can send a message to gmail with no problem. But I can't receive isso notifications

[posativ]

And if you start isso, you see a message like INFO: connected to SMTP server? I have a working setup with Postfix (but using port 25 without encryption).

[ghost]

No:

# cat /var/log/isso.log  | grep SMTP
root@deimos:/home/xan# 

[ghost]

I have a working setup with Postfix (but using port 25 without encryption).

What do you mean? I have to change port = 25 in isso.conf? Or what else?

[posativ]

If you configured Exim4 to listen on port 587 without transport security, then use this. If you have no idea what you are doing, then you probably want to use port 25.

[ghost]

How can I know in what port Exim4 is configured?

With port 25 in isso.conf I get the same results after rebooting isso process.

[posativ]

It is your system, you should know what is running there. Please start Isso manually, e.g. isso -c /path/to/your/isso.conf run and check the message for the SMTP connection.

[ghost]

My system is running exim4 with defaults, which uses port 587. I can use mail without problems.

[posativ]

Isso doesn't use mail.

[posativ]

Since you are not helpful at all, does echo "Subject: Foo" | sendmail -f foo@localhost somenxavier@gmail.com work?

[ghost]

Since you are not helpful at all, does echo "Subject: Foo" | sendmail -f foo@localhost somenxavier@gmail.com work? Yes as I commented before

[posativ]

I'm still waiting for the output of isso -c my.conf run.

[ghost]

Here it is:

# isso -c /etc/isso.conf run

[ghost]

With port = 25 I get:

root@deimos:/home/xan# isso -c /etc/isso.conf run
2016-04-13 12:05:25,660 INFO: connected to SMTP server
2016-04-13 12:05:25,714 INFO: connected to http://somenxavier.xyz/

But for sending emails it is considered new standard port 587

[ghost]

It seems everything is OK. Close the bug, please

[posativ]

I have it already closed, because it is obviously PEBCAK. You tried to use a port for encrypted transfer but didn't use encryption (port 25 is still fine on localhost without encryption). Please learn your system. You could have easily figured out your issue with netstat -tulpen | grep 587.

[ghost]

Please be more polite. I perceive some "tension" here. What is PEBCAK?

[ghost]

Please, put a comment on "SMTP Server documentation" for noting that: 587 if startls and 25 if none auth system

[sebix]

@somenxavier You are running your own server including a mailserver. You should really know how SMTP works. What you are dealing with here are basics and things you should know (because you'ce set up the mailserver): Which authentication and encryption is available on which port. And you can easily counter-check with tools like netcat, s_client and nmap.

[posativ]

PEBCAK

Problem Exists Between Chair And Keyboard. Used by technical support helpdesk staff to indicate that the problem with a user’s computer or experience is due to user error.

Sebastian is right, you are the administrator. You are in charge of the system and you should debug the issue before you open a ticket. The documentation is fine, if the administrator doesn't know whether 587 requires encryption or not, he should not administrate at all.

Also, the issue tracker is not a user mailing list.
