Hello everyone, This is a really simple one... I know that $alternates is a regex, but I don't really know that much about regular expressions... :-) I thought that set alternates= '((address1|address2|address3)@isp.com)' was correct, but I must be wrong since some times when I am replying to an email to, say, address1 mutt will put one of the others on the from field... But I should say that 19/20 times mutt gets it right, which only adds to my confusion... Thank you for any help on this. Cheers, Manuel
