When I send a Mail to the configured list, mutt asks me if I want to encrypt with the key-ID 0x555 and if I say yes, mutt instructs gpg to use that key-ID. And since that key-ID is configured as a group, gpg encrypts to all those configured recipients. But its quite hard to keep track of all the keys to use. Yeah, true, but I have a pla for that. Which ? Cheers, christoph Thanks for ypur help, the real kabel -- GPG-Key: http://www.kluenter.de/chris.gpg GPG-Fingerprint: 88DA B106 D973 B2AF 7CCB 725A F76C 803C 758F 71C0

Somehow it is not working, and I don't find much information about this crypto-hook. What version is it working with? It's standard mutt at least since v 1.5.20 but I don't know how long this feature exists. Do you have more information about that hook, maybe a link to the documentation, which I couldn't find? So I could investigate why it is not running on my own. This is the documentation from the mutt manual: http://www.mutt.org/doc/devel/manual.html#crypt-hook 21.Choosing the Cryptographic Key of the Recipient Usage: crypt-hook pattern keyid When encrypting messages with PGP/GnuPG or OpenSSL, you may want to associate a certain key with a given e-mail address automatically, either because the recipient's public key can't be deduced from the destination address, or because, for some reasons, you need to override the key Mutt would normally use. The crypt-hook command provides a method by which you can specify the ID of the public key to be used when encrypting messages to a certain recipient. The meaning of keyid is to be taken broadly in this context: You can either put a numerical key ID here, an e-mail address, or even just a real name. This is the documentation from the gpg man page: http://www.gnupg.org/documentation/manuals/gnupg-devel/GPG-Key-related-Options.html --group name=value1 Sets up a named group, which is similar to aliases in email pro‐ grams. Any time the group name is a recipient (-r or --recipient), it will be expanded to the values specified. Multiple groups with the same name are automatically merged into a single group. The values are key IDs or fingerprints, but any key description is accepted. Note that a value with spaces in it will be treated as two different values. Note also there is only one level of expan‐ sion --- you cannot make an group that points to another group. When used from the command line, it may be necessary to quote the argument to this option to prevent the shell from treating it as multiple arguments. So basically you tell mutt to call gpg with an group name as recipient and gpg expands the group name to a list of recipients. Ciao, Gregor -- -... --- .-. . -.. ..--.. ...-.-

I guess I should somehow tell gpg to use: gpg -e us...@domain1.com us...@domain2.com ... I guess it would not be hard to write a wrapper that checks if the email address is secur...@foo.edu.fi and if yes encrypt the mail according to my needs. But, I guess there are people that do this too, so I prefered to ask as my time is short these days :) Thanks for the answer, if nobody has a complete solution, I will use your hook to buld my wrapper.
