System works but various SMTP response codes in emails logs.
The system works and I do get notification emails (so is the user).
However, if I look into the system logs, I see logs entry's, have a look especially at the SMTP response codes.
The SMTP error codes below are from 4 different log messages. But all start with the same "failed to set sender" issue.
Unable to email via SMTP:mail.mydomain.nl:25 [email@example.com]
Failed to set sender: firstname.lastname@example.org
[SMTP: Invalid response code received from server (code: 554, response: Security failure)]
[SMTP: Invalid response code received from server (code: -1, response: D$Hڽ
[SMTP: Invalid response code received from server (code: -1, response: 2B
[SMTP: Invalid response code received from server (code: -1, response:
The security failure (happens more often) I would understand, if the pass was wrong, but it isn't.
As you can see also, on the other response codes (from other errors), the closing tags are missing, no ) and ] at the end visible in the logs.
Seems to me something buggy is going on there, especailly if I look at those strange ascii codes.
I use the pipe system to do my email sending, which works in fact fine, except for those logs.
Now I got 2 questions.
1.) Is there any way I can fix this so these errors are not in the logs anymore? Because they shouldn't because everything is working fine.
2.) I would like to keep using the pipe system, but send the ticket notification to another address at the same time as backup, how can I do this?
