<p>None was working; file was available, and the whole Mercury folder is excluded from antivirus scanning, file indexing, etc.</p><p>Anyway, the problem showed up no more...</p><p> </p><p>Best regards</p><p>Filippo </p>

<p>Hello. Today I just encountered a sudden problem that I cannot resolve. I have my M/32 with MercuryS configured to relay only authenticated connections (no ssl); the password file has been created months ago, and for months all worked without a single problem. Today, the server suddenly started to refuse connections, assuming an incorrect login. It happened two times, and the only way to solve was restarting M/32. Here is one session log as example (I masked username and password, but I assure you that both were right). ------------------------------------- 15:23:50.328: Connection from 192.168.1.102, Tue Jul 31 15:23:50 2012<lf> 15:23:50.328: << 220 myserver.it ESMTP server ready.<cr><lf> 15:23:50.328: >> EHLO ugenerico2<cr><lf> 15:23:50.328: << 250-myserver.it Hello ugenerico2; ESMTPs are:<cr><lf>250-TIME<cr><lf> 15:23:50.328: << 250-SIZE 0<cr><lf> 15:23:50.328: << 250-AUTH CRAM-MD5 LOGIN<cr><lf> 15:23:50.328: << 250-AUTH=LOGIN<cr><lf> 15:23:50.328: << 250 HELP<cr><lf> 15:23:50.484: >> AUTH LOGIN<cr><lf> 15:23:50.484: << 334 VXNlcm5hbWU6<cr><lf> 15:23:50.484: >> HereGoesTheCorrectUsername<cr><lf> 15:23:50.484: << 334 UGFzc3dvcmQ6<cr><lf> 15:23:50.484: >> HereGoesTheCorrectPW<cr><lf> 15:23:50.484: << 501 Authentication failed - bad user or password.<cr><lf> 15:23:50.484: --- Connection closed normally at Tue Jul 31 15:23:50 2012. --- 15:23:50.484: ------------------------------------- I really don't know what to think.</p><p>Any idea?</p><p> </p><p>Best regards</p><p>Filippo </p>

<P>Are any of the username/password pairs working?</P> <P>If no, check that the file is available and not held open by another program (anti-virus, another Mercury etc.)</P>
