Hello
As I have to connect to different POP / SMTP servers, I have authentification problems ... and PMail error messages
I know that there is a way to display these messages "in clear" in order to check what is sent to the server (sometimes, there could be a wrong or mistyped character)
But I can't remember what the procedure s and how to use it ;-(
Can someone help me ?
Thanks for your help
Have a good day

Hi,
I think you're referring to the session logs. Go to the Tools > Internet options... menu. At the bottom of the General pane check Create Internet session logs (advanced diagnostic use only). Logs will be created in sub-directories of your current mailbox.
Remember that these logs are open plain text so login and passwords won't be masked.

I think you are looking for internet session logs which are a record of the communication between Pegasus Mail and the connected server.

To enable them go to Tools > Internet options. At the bottom of the General tab is the option to create internet session logs.

While enabled, a log file will be created for every internet connection whether POP3, IMAP, or SMTP. You will find the log files a directory named TCPLogs located in your mailbox directory. The extension in the filename will identify what type of connection the log belongs to. They are all plain text files so you can add a .txt extension to the filename so that a double-click will open it in your default text editor.

Note: In some logs, the username and password will be Base64 encoded. If you need to decode this you can use an online decode tool like what is at https://www.base64decode.org/. This easy method of decoding means you should not post a log file without first obfuscating this content. If using Gmail OAUTH, no authentication credentials are identifiable.

Thank you for your answer
I try to define a GMail account in Pegasus Mail

For the POP server, I use pop.gmail.com Port 995 No SSL ( I tested the 2 other options as well but none works)

For the SMTP server, I use smtp.gmail.com Port 465 I tested the 3 options, but none worked !

Have you any idea about what settings combination I should use ?

I tried to send a mail to this Gmail account from another non Gmail account - It seems the mail is correctly sent as it appears in a POP Peeper session

Do you know any tool I could use to check what happens

Thanks for your help and your advice

Gmail requires authentication either by using an app password or by OAUTH 2.

An app password is a password obtained from Google for specific use in Pegasus Mail. It will be different from the one you use to login to your Google account. A web search about it will reveal details.
Edit: This manual configuration works for me:
Username: your full gmail email address
Password: the provided app password
Port: 995
Security: Via direct SSL connect

OAUTH2 authentication is built-in to Pegasus Mail. When you go to Tools > Internet options, look for a GMail button in the General tab. Clicking that button will walk you through the steps that create OAUTH authentication and the requested POP3, SMTP, and/or IMAP host configuration files. One of the steps will required you to login to your Google account so make sure those you can do that before you start. IMPORTANT: The GMail OAUTH host configuration files that are created will be specific to the email address that is showing in the "My internet e-mail address is" field on the General tab of Internet options. This is important for anyone using multiple identities.

As for which one is preferred, the built-in OAUTH is easier but is less transparent. The app password is more transparent but requires more effort. An unknown is how long Google will support authentication by app password.
