From: -pj via openSUSE Users <users@lists.opensuse.org> Date: Wed, 28 Feb 2024 21:36:12 -0600 Hi, my question for you is if it is possible for me to see the size of an email message, that I am composing while using Thunderbird? I just sent a message to the linux-btrfs@vger.kernel.org mailing list and am hoping it was not larger than 100k in size. -Thanks The most verbose MIME encoding is base64, and that increases the size of an attachment by only a third. So if you add up all the sizes (in bytes!) of your attachments and text and multiply by 1.35 (or 1.4, depending on how conservative you want to be about MIME overhead), that should give you a pretty solid upper bound on the size of the resulting message. -- Bob Rogers http://www.rgrjr.com/
