Does the problem exist for any of your customers that auth or only some = of them ? In this last case, does they have the same av ? same version ? same = update version ? and can you ask them to try to temporarly disabling "outgoing = smtp scan" for some hours (remember to close mua, chance av settings, = restart mua) to see if that help ? I suggest this because I remember that sometimes some av updates had = bugs in they 'proxy' depending of the av version and/or after some updates. A = real example in mind : With Norton 2004 Av (I don't remember exact version of updates causing = the trouble), with outgoing smtp scan enabled in the av, trying to do smtp = auth worked only if you explicitly re-enter user login and password in 'smtp auth' dialog box (at least with Outlook/OutlookExpress and = Thunderbird). Av 'proxy' didn't auth at all if you used default option in Outlook/OE to = 'use same login and pass as for pop3'. To be sure to not have auth problems, now our setup procedure is to = allways re-enter the login/pass in smtp auth (set 'use these login/pass for = outgoing smtp auth') in any mua. I never had any more the problem.
