fetching mails stuck

[Jemos]

Hello together,

I have just installed the BounceHandler, but however I have a problem fetching the mails from my IMAP-mailbox.
The protocol says:

"A0003 FETCH 3 RFC822"

Interesting thing is that the mailbox contains 19 mails and every time I start the mail fetching the BounceHandler stops working on a different mail. Sometimes it is mail one, sometimes it is mail 3 and this changes in every run.
The authentication on the IMAP-mailbox is working as you can see in the log below - I have erased some company specific data and replaced it with "[...]".

Additionally some information about the environment:
IMAP-Server: Linux server
Client OS: Windows 7 x64 completely updated
eMail BounceHandler: 3.8.4 (bought one week ago)
AV-software: turned off and on - no difference
Outlook is configured to receive mails from the same folder - closing Outlook and having it opened makes no difference

Do you have any idea? What could I have configured wrong or what can I do to solve this issue?

Can you use POP instead of IMAP? Most servers offer both protocols.

Hi,

no - POP is not working.

 

[stanbusk]

The connection log shows how your server stop responding to commands. Have you tried to contact the server administrator?

 

[Jemos]

I am the administrator and I can garantuee that the server is up and running and mails are being sent out and received. I am able to reconstruct the same issue on another desktop client.

And I can not find connection problems or aborted commands in the logfiles on the server

 

[stanbusk]

Weird then. The connection log you see shows eMail Bounce Handler commands and server responses. The server never respond to the last FETCH command :-/
