My apologizes for some off topic request but probably anyone of you knows whether Dovecot is going to enhance their support of EAI? Or whether UASG has an plans to motivate them to do it?
I talked to the Dovecot people a while ago. They would be willing to add support for the new EAI features in RFCs 6855 and 6866 if someone paid them, but they won't do it on their own. It would require a lot of work reorganizing the internal structure of Dovecot so it would be quite expensive, I estimate on the order of $100,000. But when I did EAI conformance tests on Dovecot, I found the same things that Arnt did. Even though it doesn't have new UTF-8 support, the legacy character sets are good enough and most of its internal operations are 8-bit clean so that it passed most of the EAI tests anyway. I do not think it would be a good use of time or money to add 6855 and 6866 support. R's, John
