Comment 10 for bug 1949604

Well I'm afraid I must disagree about this being a pbsync issue. Sending email from my private email account (gmail) works fine for the same file. So that would mean there is something wrong with how calibre composes the email?
About the pbsync email scheme, it works same as for kindle, the users sends email to ...@pbsync.com and the attached files are downloaded to the reader.
