I have my iPad now with iOS 5.1. In the email I have a .epub but when iPad's email program download the file, there is no way to open it on iBooks? Tapping or double tapping on the attachment downloaded will have no reaction. Can this be solved if I don't have a PC to place that file into Dropbox to open in iBooks?

Might be a stupid question, but have you installed the iBooks app in your iPad? It's not installed out of the box but must be downloaded from the App Store (for free). – patrix Apr 14 '12 at 9:46
@動靜能量 This maybe of assistance… – Simon Nov 22 '13 at 11:52
I have he same problem, but what I notice is that the email seems to recognize the epub file as a zip file rather than epub. This is why ibooks wont open it but I do not have an answer. – user65936 Dec 29 '13 at 0:29

In all cases I have tested, iOS recognizes epub files and will offer to send them directly to iBooks.

I have tested this from the email all, dropbox app as well as mobile safari.

Other apps like Evernote and AirSharing also are able to receive my epub files, so if you are not able to do this, perhaps it's an encoding issue or something about how the files are being attached to the emails and not necessarily a problem with iOS.

hm... the epub i was trying to open was an epub purchased from O'Reilly, the MacRuby Definitive Guide... I wonder then if there is something wrong with it. I later tried using Gmail in Safari on iPad, downloaded the file and was able to transfer to iBooks – 太極者無極而生 Apr 13 '12 at 19:03
There's a good chance the file didn't download correctly. I had a similar issue with a large ePub file recently inside iOS, which resolved itself when I connected to a more reliable network. – user479 Apr 17 '12 at 23:45
is it possible that this does not work if the mail account is not pop but imap? – JP Hellemons Aug 26 '13 at 13:46
Since IMAP is more tolerant to network errors and has better error recovery factors, I would say the chance that you have this error is more likely with POP email than IMAP email. All email will work once the mail and attachment download since the iOS device doesn't care at that point what protocol was used to deliver the package. (Just like when a physical package arrives - you don't care if it went by plane, boat, rail or truck as long as it arrives undamaged - all modes are capable of undamaged delivery) – bmike Aug 26 '13 at 13:49
Thanks @bmike when I click on the attachment it gives me a list with all available apps to open it with and when I select the iBook app. It just disappears and does nothing. No error or whatsoever – JP Hellemons Aug 26 '13 at 13:53
