Your rules engine is too strict with what it allows to be configured for the From field. You should allow more than just an email address as the SMTP From contains an email address and can contain a display name as well. I know you can do this because for other fields you have “with words found in …”
This is my list of necessary enhancements for the rules: https://forum.emclient.com/emclient/topics/enhancements-for-rules
I fear, however, that emClient v7, is just a UI overhaul nothing more…
Thank you for the suggestion, we’ll consider improving this in future releases of eM Client.
Great, thank you!
