Recently I have updated the Postfix (well, Nethserver as a whole) for my SMTP relays.
From there, I have been told that in a specific email the character “
ý” has been replaced with a “?” as I assume this is not a valid ASCII character that hasn’t/isn’t supported. I compared the config via
postconf -n and was not able to see anything out of the ordinary.
I have reviewed the servers and whilst they have outstanding updates, I do not believe any are pertinent to the postfix/SMTP service.
Wondering what steps I could take to view the content of the email, and too see if we’re changing any of the content. I assume it’s parsing it directly onto my smart host, but isn’t able to render the character and therefore replaces it - is there a method to alter this, at all?
Sorry it’s a real weird question. It’s got me scratching.
