Hello
I got a mail, with some PDF attach on it. (24 for a total of 25Mb)
with some code like...
Dim msg As New MailBee.Mime.MailMessage
msg.LoadMessage(Profile.tmpFile)
lbl.Text = msg.Subject
After the LoadMessage, memory usage raises 25Mb, that's ok. As son as I read de subject or To or whatever property (I undertand that reading any of the properties triggers the parsing) the memory usage of my application raises 192Mb and doesn't come back.
So where did those 192Mb Go?

That's not a leak. When you call LoadMessage, the component simply loads the MIME source of the message into memory. When any property which needs the message be parsed is accessed, MailBee checks if the message has already been parsed or not. If not, the message gets parsed and all the properties and collections get filled (the raw MIME source still remains). When you access any property next time, no parsing will be made since the message has already been made.
If you need to get the message back, set msg to null after you got all the data you need. If you do not need to access the body and attachments and just need to examine the headers of the message, you can set 'msg.Parser.ParseHeaderOnly = true;' prior to the moment when the message gets parsed.
Regards,
Alex

You can also try to update to the latest version of MailBee.NET.dll to see if memory usage decreases with the newer version. The newer version is at least significantly faster in parsing.
You can get it from http://www.afterlogic.com/updates/mailbee_net3.zip
Please let us know the outcome. Thank you.
Regards,
Alex

Hello I just dowloaded today versión 3.0.0.58. And I always get the same result, but I only noticed it with the single mail I described in my first post.
I'll try to explain it a bit better
Guess I got a memory usage of X
Then I do
Dim msg As New MailBee.Mime.MailMessage
Memory remains de same
msg.LoadMessage(Profile.tmpFile)
Memory usage = X + 25Mb
Perfect as the mail weigths 25Mb
lbl.Text = msg.Subject
Doom over you. Memory Usage = X + 25Mb + 192Mb
And won't go back, no matter if I try to dispose or set to nothing the msg. I understand 192Mb got used while the msg was parsed on and somehow aren't coming back.
lbl.Text = msg.Subject

Tomorrow when I am back to the office I can try to mail you or something the MSG that I described before. But I am not sure if I can mail 25Mb attachments, just tell me how can I submit the msg so you can try it?
