Since I run my own email server, I get around some of those issues by configuring Postfix's recipient_delimiter to use . rather than +. I've never had a site treat accounts.company@mydomain.com as anything other than a normal email address. It certainly doesn't justify the effort I've spent dealing with deliverability issues, but it's a nice perk.
