Hello, i just have installed delegate 8.11 on a windows 2000 / SP1 server and use SMTP and POP proxies. Both work fine with normal mails. Trying to send a mail with an attachment (size does not seem to matter, as i tryied with 40k to 500k azzachments) does not work. For investigation i stated the daemon in forground as follows: d:\apps\delegate\dg8_11_0.exe -vv -P25 SERVER=smtp://smtp.vol.at/ ADMIN=sebastian.penz@st-anton..at and do get following log ... 02/23
