We just started with a self hosted phplist, on shared hosting.
All seemed to work fine.
We sent some campaigns, could see who opened the mails etc.
We installed updates without a problem, we’re on version v3.6.10.
But all of a sudden all our outgoing emails contain part of one of our campaigns at the end of the mail.
Email to subscribers but also emails to administrators.
I cannot find why.
Peeked in the database but not a clue.
Has anyone an idea what is happening here and what we can do about it?
