[IMail Forum] Odd send error...anyone seen this before?

[Larry Berlin]

 

 I have an old version 7.07 install that doens nothing but process an automated email response-type system. Periodically, I get entries in my smtp logs like this:

 

20060227 104816 127.0.0.1       SMTP (3128) s: s
20060227 104816 127.0.0.1       SMTP (3128) [X] send error 4294967295 != 84

20060227 104817 127.0.0.1       SMTP (3128) [u] closing socket (u)

 

 Has anyone encountered similar problems and possibly have any ideas why this is happening? It's only recently cropped up, but it's enough to garner complaints from some of my users. Thanks.
