Pop3Client does not close TCP connections

[princeoffoods]

Hello,

Running the Pop3Client sample code in a timer keeps a lot of connections with CLOSE_WAIT state and ESTABLISHED state open (verified with sysinternals TCPView).

Checking 5 Mailaccounts every 30 seconds quickly produces about 150 open connections (about 50% with CLOSE_WAIT state).

About 10 minutes later all the connections get closed and then they start building up again.

Environment: Win8, Pop3s

Hmmm... are you disposing the Pop3Client? That disposes the underlying stream.

Sure, it's really just the sample code from the start page in a loop.

I'm sending you an email with code to reproduce it including login data to a testing mail account.

fixed

I did some more testing today. Unfortunately this issue does not seem to be resolved yet.

this may be fixed by my latest commit - the Connect loop was connecting to every IP address in a loop, even if a connection was successful.

Thank you, the latest commit fixed it.

thank goodness!
