Hi Paul Thanks for your answers. ---Paul Wrote--- Are you sure it requires a TLS connection from the outset? Normally port 587 is used with STARTTLS, where the connection is plaintext and then upgraded. Sometimes you can connect to port 465 with TLS. --- Now I has communicated with my hosting company. They write me that the outgoing SMTP-server only can be accessed on port 25 and 587. Therefore I will mean that I not can use the TLS-option in SquirrelMail, since my hosting company use STARTTLS over port 587. As I have understand the difference between STARTTLS and TLS, STARTTLS is a protocol where the client, e.g. SquirrelMail, first communicate over an unsecure connection, but after that communicate over TLS, because STARTTLS tell SquirrelMail that the server can communicate over TLS. When I select the TLS-option in the SquirrelMail interface, SquirrelMail and other applications, require a "directly" TLS-connection via another port number, e.g. 465. Is it correct understood? You can test for each by doing a plain telnet on the command line like this: telnet example.com 587 telnet example.com 465 --- My hosting company has closed for Telnet outside their network. > I hope that you please can correct the link in a upcoming release of > Squirrel Mail. It has been fixed in our source repository, thanks for the report. Nice to see that :-). Where can I upgrade SquirrelMail from?
