Description

fetchmail panel offers to deliver external emails to local users or groups, assuming they have an email address.
When the user has multiple email addresses one of those is chosen, not sure which one.
If users come from an AD server, the panel list is empty and mail could be delivered only to admin.

History

#1 Updated by Filippo Carletti about 5 years ago

A possible solution could use email addresses instead of users.
If NethServer is joined to an AD, the filed could be filled with an email address.
  1. AD: empty box, user writes an email
  2. Local users: list of all email addresses (too long?)

#2 Updated by Filippo Carletti about 5 years ago

Thanks to Giacomo, we have a template-custom that enables email addresses in fetchmail db.

#3 Updated by Filippo Carletti about 5 years ago

If we go for the email addresses list we should hide email marked as visible=internal.

#5 Updated by Davide Principi about 5 years ago

We fell into email addresses because of two reasons
  • there were SMTP access restrictions to user's mailbox internal address
  • we want mail filter checks
Now we could
  • bypass access restrictions with /etc/postfix/access table, setting fetchmail IP address
  • keep mail filter (and fix bounce issues?)
  • read mail accounts from doveadm users \* output
Personally, I don't like a free email address field:
  • Hard to validate against AD,
  • Easy to abuse/mistake: tons of bounces...

Fetchmail is dangerous and should be limited to transfer a message between two (remote) mailboxes: let's avoid unleashing of already-delivered messages!

Test case

AD accounts with an enabled mailbox are now listed under POP3 connector > Edit/Create > Account.

Verify the dropdown menu is consistent with AD state, and the UI keeps operating if connection to AD is down.

Tested: OK

Note that in case of PDC unreachable, the dropdown menu with AD users appears void. This is correct for me, it's consistent with dovecot users query failure:

# doveadm user \*
doveadm(root): Error: User listing returned failure
admin
doveadm(root): Fatal: user listing failed
