SMTP Plain not working (onPremise install)

maiko · February 4, 2020, 12:28pm

Hi,
i installed Matomo on CentOS8, everything works fine so far, only the plain-smtp-e-mail-function doesnet work. I got a smtp-server in the same subnet, if i use telnet [IP] 25 i can connect to it and send an e-mail.
The error on top is red and it says:
An error occurred while sending ‘CSV Email Report - 3.yesterday.10.de - ctdP9kJzSUi6XnCefk974t9zeg_PiM68x0iNIu1M.csv’ to [my-email-adress]. Error was ‘Permission denied’

I dont think its the permission.

Any things i can check or try to get this working?

Hi,

You could try using PHP mail() instead of SMTP for sending mail and configuring PHP to use SMTP.

The SMTP library Matomo uses is a bit ancient, so weird bugs aren’t impossible. This will be fixed in Matomo 4.

github.com/matomo-org/matomo

use a modern PHP library for sending emails and SMTP

related to https://github.com/matomo-org/matomo/issues/8613 and https://github.c…om/matomo-org/matomo/issues/12007 inspired by https://forum.matomo.org/t/email-reports-not-sent-broken-pipe-errno-32/34047 Matomo uses a copy of Zend Mail that has last been updated in 2011 (in https://github.com/matomo-org/matomo/issues/2581) While SMTP isn't the fastest developing protocol, a lot has changed in that time. So instead of keeping an outdated library or reinventing the wheel, I'd recommend replacing it with a maintained, popular PHP library like PHPmailer or swiftmailer. Bonus side effect: We would get proper error messages for hard to debug errors instead of things like `fwrite(): send of 6 bytes failed with errno=32 Broken pipe`.

Hey Lukas,

thanks for you reply, installed postfix (i hate sendmail), configured it, changed the settings in matomo and now it works!!!
