Re: Max length of an email subject line

I've got a customer who wants us to expand the Subject line to 256
characters.  First step is to find if it is even valid to be that long.  *I*
wouldn't want to receive one that long, but they aren't asking my
opinion...and they are paying the bills.  So they'll get it.

Subject: Re: [PCTECH] Max length of an email subject line

Anybody know what the maximum length of an email's subject line can

be?

The subject is an unstructured field so it has no maximum length.

While technically true, keep in mind there's a difference between RFC
limits, and practical limits.

For example, I just tried an email with a 1500 character subject line,
folded per the spec. Exchange ate it just fine, and showed me the whole
subject in outlook web access, but Outlook 2003 only showed the 255
characters. MAPI handled it fine because it was relayed to my palm w/the
complete text. And gmail took it ok. So in short, if you've going with
something "really long" make sure you've tested well.
