--- Comment #1 from Matija Šuklje <mat...@suklje.name> --- When interacting with a calendar invite in KMail I get the following error: 5.1.7 Bad sender address syntax Looking at the Outbox, this is the address it tries to send from – so clearly an issue with encoding (change “ [at] ” for “@”, of course): <matija [at] =?utf-8?B?xaF1a2xqZQ==?=.name> If I switch the default Identity back to <matija [at] suklje.name> it works fine. -- You are receiving this mail because: You are watching all bug changes.
