Christian Hoppe <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #2 from Christian Hoppe <[email protected]> --- This bug is still present as of KMail 6.7.3 (26.04.3). Exchange canonicalizes the Mail to conform to RFC 2311/RFC 8551 "The line ending MUST be the pair of characters <CR><LF> ..." An SMIME-signed mail sent via exchange subsequently fails validation in practically every MUA (even KMail itself). While that is probably questionable behaviour by exchange, KMail nonetheless must canonicalize the Mail prior to signing it. A workaround is using SMIME/Opaque which is not as compatible leaving e.g. mailing list posts, Mails to users with mobile clients, etc. unusable with SMIME signatures. -- You are receiving this mail because: You are watching all bug changes.
