Mail not displayed

Hi,
I wanted to report a case of an "empty email".
From and subject fields are left empty in the overview.
Mailwasher seems to be able to fully read the content as show in the source, yet fails at parsing its send and subject (which is UTF encoded)?
Let me know which info/detail you need to check it out.

Are you able to copy/paste the full source into a text file and send it to me at [email protected] ?

Great thanks, it's a massive email header, just over 300 lines before the To, From, Subject information is present.

MailWasher aborts email headers after 250 lines when looking for this information, so we'll get that limit lifted to around 500 lines.

If you care for such things, a while back spammers were inserting thousands of lines of fake header data, the header alone could be 1MB. This was causing significant lag in MailWasher, so we opted to only scan a certain number of header lines. In the time since, regular headers have increased quite a lot, hence the problem now.

Ah... I didn't know yes...
This kind of endless data buffers could also be used to cause buffer overruns, etc.
Thanks for pointing that out!

Try this beta, hopefully solve the problem. It'll install fine over the top.
