It's been a couple times now that we see a batch of messages getting stuck in the spool for many hours. They always show a "Next attempt" date which is in the past. For example I have this message right now which is stuck. It's 14:08 here and the Next Attempt will be at 14:03.
Usually we have to log onto the mailserver with an FTP software, download the messages from the spool folder, erase the message from the web interface and from the FTP and finally re-upload the message (.eml only not the .hdr) into the drop folder. It's the only way we were able to fix the next attempt date and get these messages delivered.
Did anyone notice something similar with Smartermail 13 or is it just us?
