I’m trying to send with RCM4000 and smtp\_tls.c The verbose printout is: # IP addr. Mask Up Lnk Type MTU Flags Peer/router * * * 0 217.208.53.33 255.255.255.128 yes yes eth 1500 \*DD 217.208.53.1 Setting authentication parameters… Sending mail to [another@telia.com](mailto:another@telia.com) via [mailout.telia.com](http://mailout.telia.com) to:1729 from:173b subject:1719 message:171F SMTP: Resolving [mailout.telia.com](http://mailout.telia.com) TCP: 337ms since last call to tcp\_tick! SMTP: Opening to 3E14E982:1d1 SMTP: Connected SMTP: Timed out Error sending message Why the long time since last tic? When connected there must have been some conversation with [mailout.telia.com](http://mailout.telia.com)? There is a pop3 [mailin.telia.com](http://mailin.telia.com) for email coming to me. This is not entered anywhere. Not needed to send email ? ---

I would check the return value from smtp\_status() to find out why you are getting the “Error sending message” statement. You were able to connect so I don’t think there is anything wrong with the socket at that point. ---

the return value from smtp\_status() is -438, that is SMTP\_TIME error. After some changes, allowing uncoded message and nonmatching name in certificate, the return code was -439, SMTP\_UNEXPECTED. After trying with a certificate generated with the utility “certificate.exe”, still no success. The end of the Stdio output is: SMTP: Resolving [mailout.telia.com](http://mailout.telia.com) TCP: 279ms since last call to tcp\_tick! SMTP: Opening to 3E14E982:1d1 SMTP: Connected TCP: 1061ms since last call to tcp\_tick! SMTP: Read: char(21),char(3) SMTP: Read: SMTP: Read: char(2),char(2),( Error sending message, rc=-439 After this I changed the port from 465, given for SSL by Telia to 587, not mentioned by Telia and it w o r k s ! Thanks!
