Dear All, I am running Mail on 10.4.11 and have noticed an issue when dealing with .pdf files. Every time I try to forward one it increases in size by almost 40% - files that start off as 10MB or so end up being nearly 14MB in size. I do not use any custom settings and usually don't tick the "Send Windows-friendly attachments" option. What's going on here? Is there anything I can do about it? Some recipients are unable to handle messages above 10MB, others are limited at 25MB and it is annoying to have to split files after thinking that you had got the files down to an acceptable size. Thanks for your help!
