Assume I want to connect from my local email client to two (!) remote email servers
The corresponding instructions in .conf file looks like (my guess):
[smtps-firstacct] accept = 127.0.0.1:259 connect = smtps.myisp1.com:465
[smtps-secondacct] accept = 127.0.0.1:259 connect = smtps.myisp2.com:465
Questions:
1.) a configuration like above with the same "accept" port 259 is NOT possible because stunnel does not know to which remote email server he has to connect. To distinguish two different remote email server I always have to select TWO different accept-ports like
[smtps-firstacct] accept = 127.0.0.1:259 connect = smtps.myisp1.com:465
[smtps-secondacct] accept = 127.0.0.1:258 connect = smtps.myisp2.com:465
Correct?
2.) Can I use arbitrary accept-ports like 1242 or 23199 or is there a port range from I have to select one?
3.) Moreover assume I want to make the SSL connection transparent can I select an accept-port 25?
4.) I read somewhere that I have always to specify in email client for POP3/SMTP an address
127.0.0.1:9999
and NOT
127.0.0.1:259
in order to connect to local stunnel service. Because local stunnel service is always listening on port 9999.
Is this correct?
