550 Relay blocked

this is very strange..... one of my customers has started receiving messages like this: The following recipient(s) cannot be reached: '[elided]' on 2/28/2008 3:13 PM 550 relaying blocked, read new mail, add 68.92.8.162 to forwarding or enable smtp authentication in intermittently when sending mail. they've not told me of any particular pattern (i.e. specific recipients or specific senders) the ip above is the address of their firewall appliance. we haven't changed surgemail's config in some time - other than adding new customer domains. can anyone shed some light on what might be causing this? david camm advanced web systems keller, tx

Is this an authentication error?  Do they have the "my server requires authentication" check in m$ outlook? Or whatever client they are using?

normally you are allowed to smtp for x number of minutes after you have authenticated when checking your pop account. the customer will be able to send email if he downloads email first. see g_relay_window - Minutes to allow relay after pop/imap login NOT RECOMMENDED. you are better off using smtp auth sai On 2/29/08, David Camm <dcammadvwebsys.com> wrote: > this is very strange..... > > one of my customers has started receiving messages like this: > > The following recipient(s) cannot be reached: > > '[elided]' on 2/28/2008 3:13 PM > 550 relaying blocked, read new mail, add > 68.92.8.162 to forwarding or enable smtp authentication in > > intermittently when sending mail. they've not told me of any particular > pattern (i.e. specific recipients or specific senders) > > the ip above is the address of their firewall appliance. > > we haven't changed surgemail's config in some time - other than adding > new customer domains. > > can anyone shed some light on what might be causing this? > > > david camm > advanced web systems > keller, tx > >

we have used smtp auth ever since we satrted with dmail (surgemail's predecessor). the problem is purely local to a few machines (not all) at this one particular customer. i've concluded that it must be a local problem and have resolved it (at least temporarily) by adding some ip addresses to my relay_allow list. david camm advanced web systems keller, tx sai wrote: > normally you are allowed to smtp for x number of minutes after you > have authenticated when checking your pop account. > the customer will be able to send email if he downloads email first. > > see g_relay_window - Minutes to allow relay after pop/imap login NOT > RECOMMENDED. you are better off using smtp auth > > > sai > > > On 2/29/08, David Camm <dcammadvwebsys.com> wrote: >> this is very strange..... >> >> one of my customers has started receiving messages like this: >> >> The following recipient(s) cannot be reached: >> >> '[elided]' on 2/28/2008 3:13 PM >> 550 relaying blocked, read new mail, add >> 68.92.8.162 to forwarding or enable smtp authentication in >> >> intermittently when sending mail. they've not told me of any particular >> pattern (i.e. specific recipients or specific senders) >> >> the ip above is the address of their firewall appliance. >> >> we haven't changed surgemail's config in some time - other than adding >> new customer domains. >> >> can anyone shed some light on what might be causing this? >> >> >> david camm >> advanced web systems >> keller, tx >> >> > >
