Hi Chactory,
Well, the problem has happened again and it looks as though the problem is with completing the connection to the server. The log file has the following in it:
Client Log started at: 26/06/2015 - 14:52:57
14:52:57 S: +OK Spamihilator 1.6.0.0 ready
14:52:57 C: USER
xxx.yyy.com&name@xxx.com&995
14:52:57 S: +OK Username accepted
14:52:57 C: PASS ********
15:18:10 S: -ERR
As you can see the password interaction didn't complete, hence the hangup. Isn't there a mechanism which should time this out?
To complete the information, the SSL icon is flashing during this period. I'm running spami 1.6.0 32-bit on a 64-bit version of Windows 10 Technical Preview but I've also had the same issue on a Windows 7 machine. The reason I run the 32-bit version is that I had an issue with the 64-bit version of spami (VB Runtime error - Win7 64 bit posted 16 August 2012) and found that the same problems didn't occur with the 32-bit and so I've stuck with the 32-bit version ever since.
