I use smime with mutt and exchange at work. Currently using mutt 1.5.20, as compiled by Debian Lenny backports. It mostly works for most encryption and decryption needs -- thanks!
However, when sending smime email to blackberry users in my organization, I get complaints that they cannot read my email. In particular, they see an attachment that they cannot open. Outlook users (sometimes the same user at their desk rather than their phone) are able to receive my smime-encrypted email, but even when I send a "simple" text email encrypted with smime, when they unencrypt it, they see it as an attachment. I spent some time poking around on the web and didn't find any info on this. The smime manpage suggested -text helps with text headers. So I changed the default smime_encrypt_command accordingly: set smime_encrypt_command="openssl smime -encrypt -%a -text -outform DER -in %f %c" Now text emails work mostly correctly (I get some extra headers when decrypting), but the above breaks when I deliberately include a binary attachment. Augh. Help? - Morty
