Why does Alpine use Base64 instead of UUencode?
Alpine uses the Internet MIME (Multipurpose Internet Mail Extensions) standard for all attachments. MIME uses “Base64” encoding rather than uuencode, because uuencode uses characters that are transformed by some email gateways, and there are also several incompatible versions of uuencode. However, if needed, you can certainly uuencode a file outside of Alpine, then use the Composer’s “file inclusion” (^R) command to insert the uuencoded file into the message.
