I have a gmail account for a long time that I can use without any problems. I just created another one that I needed. While I can log in on the gmail web site for the new email , I can't retrieve any email messages through Pegasus. The error I get is "Invalid username or password". I am using PMAIL v4.80. As far as I can tell, I configured the new PMAIL identity exactly the same as the old (except for the password, of course).

I seem to remember having to do something special with PMAIL a long time ago when gmail increased their security. Does that have to be done for each new gmail address?

Would installing v4.91 help? If so, please send installation instructions.

Thanks.

Yes. At a minimum you need to enable POP3 access in Gmail and then use an app password in Pegasus Mail. An app password is a password that Google issues for use with a third party email client like Pegasus Mail. A web search will reveal the details about this. Alternatively, starting in the v4.81 public beta is the ability to automatically create OAUTH2 authentication configuration. You can read about that in the 4.81 Public Beta section on this page: https://www.pmail.com/v49x.htm

If you are currently access a Gmail account with 4.80 then you must be authenticating with an app password. Is one better than the other? I give a slight edge to OAUTH2 solely because it may help future-proof the process. An unknown is if/when Google will stop supporting the app password.

OAUTH2 is very complicated and not transparent. Configuration happens behind the scenes. When all the stars align and it works, then its great. When they don't, it is a PITA.

Just download it and run the .exe. I will recognize your 4.80 installation and offer to upgrade it. Do a full backup of your 4.80 first, just in case. You might want to consider upgrading to the 4.81 public beta instead of 4.91. 4.81 has been out for awhile, is well tested, and has proved to be rock solid. OTOH, 4.91 is newly released.

Sorry for the long delay, Brian. I have tried a number of times, but I can't get PMail to retrieve the mail from my new Gmail email address. I will try to upgrade to 4.81. What's the easiest way to back up my current version?

Did you enable the Pop3? Think by default google has it disabled?

With v4.80:

• Make sure POP3 access is enabled in gmail as just mentioned by @msetzerii .

• Make sure you have created an app password in gmail for use with Pegasus Mail and are using that password in the gmail POP3 and SMTP host definitions.

If upgrading, you must still have POP3 access enabled in gmail, but now have the option to configure OAUTH2 authentication via a "GMail" button in Internet Options.
EDIT: If you use Identities, be sure to use the "GMail" button while as the Identity that accesses the gmail account you are creating access to.

As for backing up, that depends on your installation. If you have a default installation where the programs files are in C:\Pmail\Programs and the mail data is in C:\Pmail\MAIL then a copy of the entire C:\Pmail directory is the best backup method. If unsure about the program files and mail locations you can find them by clicking the "Info" button in Help > About Pegasus Mail. Look at these three entries:
WINPMAIL.EXE directory:
Home mailbox location:
New mailbox location:
