When using POP server, a mail delivered to unknown/undefined alias makes fetchmail fail and stop parsing all emails.

[rizzopablo]

Fetchmail reads emails from server, parse it, identify corresponding aliases and make the corresponding action (save to user inbox, publish to group, etc) An email sent to an unknown recipient should be ignored or processed in other way.

This works as described when using IMAP server.

Using a POP server, if fetchmail reads an email from queue and can not identify a corresponding alias, it stops reading further emails.

Using latest Openerp 7 from trunk.

Hello Pabriz,

I have read your bug report, but could not understand it properly.
So would you please elaborate more on this better If you can provide the proper use case for this.

Thanks and waiting for your reply!

Hi,

I think the problem is that the inbox contains email addressed to different alias tha expected. In this case fetcmail throws...
Do you are using a fetchall email account ?

May be is same as my question:

No, this is not the case. There is a diferent behavior when fetching from imap or pop, the first one is correct, while pop is not.

[electro (electro1)]

Hello Pabriz,
that's partially true.

I think the POP/IMAP fetchmail steps are as below:
- Each N minutes
- OpenERP fetches only new messages from the inbox.
- If a new message is found, fetchmail will read it (the email will be marked as read)
- Internal routing try to make the corresponding action,
- if a valid alias is found, openerp routing make the action and go to read next new message
- if it's an unknown recipient, routing trhow an exception and stop to working

When you are using IMAP, the unknown message is "as read" than on 2nd fetchmail runs, the unknown message will be ignored and fetchmail will read next message in your inbox....this is an unexpected workaround

Difference between POP and IMAP is because
When you are using POP, OpenERP consider as new messages all messages found in the inbox.

When you are using IMAP OpenERP consider as new messages only unread messages the inbox.

did you check your log file for some info about fetchmail error ?

A question is still open: 'how to manage" unknown messages ?

Dear Electroshock, please, do not guess, read the code and read my first post:

"Using a POP server, if fetchmail reads an email from queue and can not identify a corresponding alias, it stops reading further emails."

It should read the remaining emails in the inbox, like it does when using imap. Just because one email doesn't match, that does not mean the others wouldn't too.

That's the bug.

Best regards.

Dear Pabriz,
I'm agree with you it's a bug :-) but I think is same bug both for IMAP and POP.

You can't see the bug with IMAP because it happens an un-expected workaround. (thanks to the invalid email isn't "new" on 2nd fetching)

If you have 11 emails where first 10 are dummies emails you have to fetch 11 times (and throwing 10times) before get the 11th valid mail in openerp.
Check the logfile

cheers

Hello pabriz & electro (electroshok) ,

I have checked this issue with latest trunk as well as with 7.0. And I am facing same issue with POP mail server. So, I am confirming this issue.

Thank you.

[electro (electro1)]

Is there some updates on this issue ?

[Michael Karrer (michaelkarrer81)]

I am also very interested if any update / workaround is available - I do want to import an inbox with 600+ messages and it will take forever because of a lot of "not aliased" mails ...

[PkLab.net (pklab)]

Hi,
I've same problem too... and I'm surprised that after 8 months there is no solution neither answer.

Has "social network" features lowest priority in openerp development ?

cheers

I linked my email account as a incoming mail server in my OpenERP, when launchpad send community maillist mail to me, the fetch mail raise exception, because the receiver is not my mail, cann't match the alias in openerp. then All email cann't been process from that time.

This is very important issue because any fetch mail server will crash only when it got a mail from a maillist.

[开阖软件 Jeff Wang (jeff.osbzr.com)]

Sorry I read the log and found fetch mail continue read next mails, so this unmatch only a assert exception

[PkLab.net (pklab)]

Hi jeff.osbzr
openerp will continue with next mail only if your account is IMAP, in case account is POP openerp will try to read always same message, without success.

In addiction the wrong addressed email will remain in "read" status on server and this will be a mistake when you will read it from other mail client or webmail

Testscenario :

0) create a <email address hidden> address
1) create johndoe database in openerp.
2) create an fetchmail account to get the mail from <email address hidden> with pop
3) create a partner janedoe with emailaddress <email address hidden>
4) send an email from <email address hidden> to <email address hidden> and cc support@johndoe in cc: (<email address hidden> is NOT a partner in the johndoe database)
5) send an email from <email address hidden> to <email address hidden>

The second mail does not arrive in the openerp database as stated in :
