Thanks for the pointer :) Anyway, the question is then: are (were) you using exactly the same call to getnameinfo with NI_NAMEREQD flag set in 3.85.03? The reason I ask is because in the URL you provided I read that "The getnameinfo function was added to the Ws2_32.dll on Windows XP and later." and, if you use(d) exactly the same call in 3.85.03, then I don't understand what is happening. Let me explain. When using 3.85.03 the EHLO shows either 'maria' (the RDN of my machine) or 'maria.ermapper-spain.com' depending on the setting for DNS (fixed or obtained automatically) in the TCP/IP properties for my LAN connection. However, when using 3.86.10, no matter what the setting is for DNS in my LAN connection TCP/IP properties is, the EHLO _always_ shows the IP of my machine. -- Best regards, Miguel A.
