[sylpheed:33213] can send email only after pop download

[Giulio Bottazzi]

Thre's something strange happening to me when I try to send messages
using one specific server. If I start sylphed  (or leave sylpheed
inactive for a while) and try to send the message, I got an error. The
log is posted below (marked LOG1). Then if I download emails from the
same server via pop and, after the download, I try to send the same
message again, everything works (see LOG2 below where I replaced
actual email addresses with [...]). Any clue? Could somebody help me
or point me in the right direction?

Thanks in advance,
Giulio.
