Clients and most servers could do a better job of being intelligent about some of that stuff. I realize you don't want to be too fancy, but... yeah. It's easy to blame the user, but the problem is usually more in the organization's instruction and guidance, which can be a lot harder to handle.
Precisely... :)
No reason not to try to make things easier on everyone involved.
On that we agree... and certainly, if there *is* something that dovecot can do to make things easier - by all means, tell Timo - as I said (and should be obvious) - he is more than willing to make dovecot better, especially if it can be done without too much trouble (I wasn't kidding or being smart when I asked the OP if he knew of anything that could be done better)...
