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.mydomain.nl Failed to set sender: email@example.com[SMTP: Invalid response code received from server (code: -1, response: D$Hڽ[SMTP: Invalid response code received from server (code: -1, response: 2B 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?
