bug#23342: 25.0.92; Gnus doesn't honor nnimap-address

[Live System User]

Hi,

It appears that Gnus doesn't honor the value of `nnimap-address'.

As an experiment, I set my `gnus-secondary-select-methods' to:

gnus-secondary-select-methods is a variable defined in ‘gnus.el’.
Its value is shown below.

Documentation:
A list of secondary methods that will be used for reading news.
This is a list where each element is a complete select method (see
‘gnus-select-method’).

If, for instance, you want to read your mail with the nnml back end,
you could set this variable:

(setq gnus-secondary-select-methods '((nnml "")))

You can customize this variable.

Value: ((nnfolder "")
 (nnimap "gmail"
         (nnimap-address "imap.gmail.com")
         (nnimap-server-port 993)
         (nnimap-stream ssl)
         (nnimap-list-pattern
          ("*"))
         (nnimap-expunge-on-close 'never)
         (nnimap-expunge nil)
         (nnir-search-engine imap)))

Original value was nil



I then executed M-x gnus.

It failed because it couldn't resolve the hostname "gmail" but it
should have used the value of `nnimap-address'.

Here is the contents of the *Message* buffer:

If I add "gmail" to my /etc/hosts file:

74.125.22.108   imap.gmail.com gmail gmail-imap.l.google.com
74.125.22.109   imap.gmail.com gmail gmail-imap.l.google.com


it works, as expected.

Thanks.
