hello,
Finally Daniel had the last word :
"A quick first guess would be that the IMAP server is not routing its
replies through the pf box (i.e. the default gateway setting on the IMAP
server is wrong)."
By changing the default gw of my IMAP Exchange server with my testing PF
Firewall, the connection from outside is ok. In conclusion I use (as written in
book or internet) :
rdr on $ext_if proto tcp from any to $ext_ad port 993 -> $imaps_server_ad
pass in quick on $ext_if \
inet proto tcp \
from any port > 1023 to $imaps_server_ad port imaps flags S/SA modulate
state
Thank you all for your quick reply,
regards,
raphael
