Hello,
we have a SMTP mail server on a DMZ and people checking their e-mails on this server with POP3 client (outlook & outlook express). Since a few days, some mails were bloqued and people were receiving the following message in outlook :
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'account name', Server:'server', Protocol: POP3, Port 110, Secure (SLL); No, Error Number: 0x800CCC0F
My Mail server reported the following errors :
POP 20 Aug 3 07:15:14 F 1021 1997 Too many connections (2) from [192.168.2.1] to [192.168.2.2]
POP 20 Aug 3 07:15:14 A 0000 -1 -ERR Busy - please try later
192.168.2.1 being Astaro and 192.168.2.2 the mail server.
After disabling POP3 proxy, everything is fine. Can anyone tell me what is the problem ?
Thanks
Pascal.
