PopMan

PopMan 1.3.15 supports POP3 with GMail OAuth 2 sign in.

Changes

(+) Add POP3 support for GMail OAuth 2
(*) Improve performance of message loading
(*) Show error message when Google sign in fails because of failed browser launch
(*) Hint to missing Admin priviliges when Google sign in fails
(*) Break long header line when printing message ...

But why don't you simply use IMAP for GMail then?

POP3 simply was not a priority for me. I found POP3 access to GMail always somewhat problematic. Only IMAP4 really worked reliably. Is there really a need for POP3 GMail access?

The sign-in button will appear below the Password field if the server name contains the string "imap.gmail". This button will be enabled if the user name contains an email address.

I suggest adding a new account in PopMan from scratch:

Enter name of the account. Enter server name "imap.gmail.com" and User name "my.email@gmail.com". Leave Password blank. Press "Sign In With Google" button. Complete the sign in in the web browser. Return to PopMan. OK the messagebox "Sign-in ...

I confirmed that PopMan version 1.3.1 is significantly faster than the latest version.

My guess is that it is related to Unicode. V 1.3.1 was the last version without Unicode support.

I will investigate further and try to improve speed again..

If a mail address or domain is blocked (on black list), then all messages from that sender will automatically and immediatelly be deleted. So there is no point in having a different font for them.

For white listed messages you want to be able to configure a different font?

Only IMAP is supported for GMail OAUTH 2.

OK, when simple POP3 is also affected then it has nothing to do with encryption.

One major change from 1.3.1 to 1.3.2 is the support for Unicode, i.e. internally UTF16 (two bytes per character) is used.

That effectively doubles the amount of RAM consumption for text but should not have much ...

I don't think an older version with TLS 1.2 will work better.

Does the slow email retrieval only happen on Win 7 and older?

Does it happen with "POP3 TLS" as well as "IMAP4rev1 (SSL)"?

You can configure the IMAP4 protocol to always return all messages instead of only UNSEEN. For this click on the small button "..." next to the protocol dopdown. In the dialog change the value for "Criteria" from "UNSEEN UNDELETED" to just "UNDELETED".

Of course that means every time PopMan ...

Note that for IMAP4 by default only emails that are UNSEEN will be retrieved by PopMan, i.e. if you have downloaded mails via other mail programm or read them via web interface, those messages are marked as SEEN on the server.

So best is to send a new mail to the account. It should be retrieved by ...

What protocol do you use to access your mail in PopMan? POP3 TLS?

If so, I suggest trying "IMAP4rev1 (SSL)" instead. Note that you might have to change the mail server accordingly.

PopMan 1.3.13 supports OAuth2 sign-in for Google now.

But for this to generally work, Google first needs to approve it. Before then, I can add up to 100 email addresses for testing.

So if you or anybody else wants to test Google Sign-In, write me an email...
