Is there something unusual in the format your your email address? Is it out of the ordinary? In particular does it contain any characters you might not normally see in the vast majority of email addresses?
A common issue with "old" websites are that the regex does not support 4 character top level domains... e.g. myname @ domain.info
If that's the issue for you, there is not much you can do about it, other than contact the websites and tell them the regex they are using to validate emails is flawed / out of date. You might also consider creating yourself another "backup" email address on a different domain which validates 100% of the time.
I am not following the gist of this thread at all. So the issue is when using certain websites in Safari, it rejects the email address? If the site accepts it via another browser on a PC or Mac, then the issue could be the website coding where the validation routine is not having the information parsed correctly back to the web server, therefore producing the error.
I don't know whether you would necessarily blame Safari, but more likely the web site coding is not safari friendly. Either way, I would not blame the iPad itself.
