Webmail captcha

[#1]

Small issue, I use the webmail when I'm in college, and every time I want to reply to emails I have to use the captcha thing.  Is it really a must have feature?  I've no idea if webmail can be used by spammers as you need to be logged in to use the webmail service, so is it really nessassary or can it be disabled?  Or is it only displayed if you are not on the PN network at the time?

There is a fix which will reduce the requirement for entering the CAPTCHA, it will only require it every x times you send a mail instead.
I believe it was rolled out last week sometime, but caused problems so was rolled back for rework/review.

Hopefully they will fix the problem, a couple of times i forgot it was there and hit send.

I wouldn't mind, but sometimes even *I* can't work out what the letters are, never mind an OCR system!   Like "0" or "O" or "o", "1" or "I" or "L", and sometimes the sticks on P, Q, 6, etc, are so small as to be lost in the noise.
