Hi Pat,
What do you consider to be part of the e-mail address?
For example, is the following an e-mail address?
Scott Klement (Comment Goes Here) <scott@xxxxxxxxxxx>
How about:
Scott Klement <scott@xxxxxxxxxxx>
Or, do you just mean this part?
<scott@xxxxxxxxxxx>
Or just this part?
scott@xxxxxxxxxxx
In that last case, the length limit would be 320 bytes. Maximum of 64
bytes before the @, and 255 after the @. At least, that's what the
standards say -- but I've seen many situations in e-mail where the
standards have been ignored, even by major software vendors (such as
Micro$oft.)
A 320 byte address could not be used in a forward/reverse path, since
the maximum length of a path is 256 bytes (including punctuation). I
wouldn't put much stock in the 256 byte limit, however, since NOBODY
uses paths these days. They were popular in the UUCP days, but those
days are long gone.
If you add the other parts into the address, it can be arbitrarily long.
There's no length restriction on the display name or comments. The SMTP
standards preach a philosophy of taking the length numbers as minimums,
and endeavoring to write code that does not put a length limitation on
anything. (Kinda hard to do in a database, though.)

sure what is the "correct" number.
Is 256 the maximum length for a typical email address ?
