string case in Evolution Mail filters
I have created a number of filters in Evolution, and they seem to be working, at least most of the time. I am mainly using the recipient field to filter on (several email accounts).
My filters are set up with all lower-case email addresses, but sometimes folks use mixed case addresses when sending, and it appears that those are not getting filtered as I expected. I have been unable to find any documentation regarding case of the items compared in Evolution filter comparisons.
It seems that the filter comparison is case-sensitive. Is this true?
If it is true, how can I work around it? Making the string coming from the email into lower-case to match the filter would be what I'd shoot for since I already have the filters set up that way.
