Why can i not send an attachment over 25mb anymore?
Anymore?
25MB has been a standard limit shared by multiple platforms for yonks, also is generally what business set and even in addition to that is still quite a high limit.
A quick google by myself because I dont use BTMail shows that the limit is 25MB in a few posts related to business mail, I doubt its more for a normal account.
I could be wrong but I would be super surprised if you were ever sending mails larger than that successfully.
Compress and send as a zip file
Not a lot of use if the file to be sent is already compressed such as a .jpg.
