Hi there!
I’ve got an issue with the transparent smtp-proxy.
In a small enviroments, I have several Outlook-Clients, that contact the Providers mailboxes via pop and smtp without SSL/TLS.
When I activate the transparent proxy they aren‘t able to send mails (503 AUTH command used when not advertised).
I can redraw the problem using smtpdiagpro.
In the UTM log I see only:
013:01:26-08:59:00 kontnybonn exim-out[26753]: 2013-01-26 08:59:00 Start queue run: pid=26753
2013:01:26-08:59:00 kontnybonn exim-out[26753]: 2013-01-26 08:59:00 End queue run: pid=26753
2013:01:26-08:59:43 kontnybonn exim-in[5053]: 2013-01-26 08:59:43 SMTP connection from [10.133.0.43]:54422 (TCP/IP connection count = 1)
2013:01:26-08:59:43 kontnybonn exim-in[26805]: 2013-01-26 08:59:43 SMTP connection from (R830kon2) [10.133.0.43]:54422 closed by QUIT
Any ideas?
Thanks in advance!!! Jochen
