Hi Paul, I looked into this, and it turns out I was wrong in my conclusion that text files are not affected. It now seems that when sending text files (but not other file types) SquirrelMail strips boths 0x0a and 0x0d 0x0a from the end of the file. When downloading files through SquirrelMail, it will add a 0x0a. So when I send a text file through SquirrelMail to myself that ended on a 0x0a, when I download it it will have the same size but the 0x0a has moved from the end to the start. If it ended on 0x0d 0x0a it will be one byte shorter and will also start with 0x0a. When I send a pdf to myself through SquirrelMail (which also ends with 0x0a), the 0x0a at the end does not get removed. When downloading the attachment, a 0x0a does get added to the beginning. JPEG's end with 0xff 0xd9, and they get a 0x0a added to the beginning as well when downloading while they are send correctly. So to summarize: - the issue with downloading attachments now seems independent of file-type and whether the file ends on 0x0a, 0x0d 0x0a or something else. - when sending an attachment something specific to text does seem to happen, and both 0x0a and 0x0d 0x0a get stripped from the end of the file.

It's driving me nuts :).
