I've added a signature block for a group and added the my address to test, email works with sig block added to e-mail. Then I moved on and setup a group to add all the users to. I'm in this group as well. If I remove my individual address and put the group in the rule, the sig block doesn't work. If i add the users individually, the sig block works.
I've checked and the same users I'm adding individually are in the group, that doesn't work when applied to the rule.
Anyone have ideas of what I'm doing wrong?
