The “From” rule within the Rules tool does not accept generic/wildcard rules.
I know this is a duplication of an issue that has been reported for the past SEVERAL YEARS, and that a CHEESY-ASS workaround has been documented at https://forum.emclient.com/emclient/topics/wildcard-in-rules (thanks to Gary Curtain for this!)
HOWEVER, as a free trial user who is considering becoming a paying subscriber, it concerns me deeply that such a ridiculously simple feature cannot get implemented within a 5-year timeframe. The workaround is very unintuitive, and I wasted at least 15 minutes of time finding the workaround on the forums. Fifteen minutes of my time is more expensive than a license for emClient, so this is already a loss for me.
Implementing *only* the asterisk wildcard in the leftmost position, probably using a RegEx expression, should be trivially easy if the rules engine is designed with even a semi-decent architecture. (Or, if you wanted a really quick & dirty solution, you could copy & paste the code for “with words in subject” and change it to be a “with words in from” rule. That would take less than an hour of developer time!) How on earth do you blow this item off for 5 years?
One of my top considerations for an email client is the ability to sort & filter the emails that I *DON’T* need to deal with in a very efficient manner. This issue erodes that, and more importantly erodes my confidence in this product. So I’ll continue using the workaround, but meanwhile, I would urge your product manager to prioritize getting some of the most basic features like this that have been requested for 5+ years implemented before addressing sophisticated bells & whistles.
My choice to license your product will be strongly influenced by your response to this post. Thanks for your consideration.
