It's often asked if we limit the sizes of attachments in emails.
Our email server will try to send attachments of any size, however, temporarily, you can only send attachments through our webmail interface of up to 15MB. (Eventually, that total will be higher but it will still be limited to 50)
You can send larger attachments through third party email programs. However, your ISP or your email program or app may have it's own size limitations that you will need to deal with. Also, very large attachments will depend on how fast your internet is and if you have space in your email allotment for an attachment that size in your Sent folder.
If you have attachments in the hundreds of MB, you may want to consider a file sharing service such as dropbox.
