Email config on V4.5.7 and interaction with Dolibarr

Dear All,

After two days of work, thousands of assays, I succeed installing ProjeQtor !
Yes, I know, I am probably the best ! (perhaps this one you should invite for diner on wednesday).

I am testing the soft with regard to my needs. It seems very interesting.

1 - That is not that I need absolutely send e-mails via the soft, but since the function exists, I would like to use it for collaborative matter.

However, after many trials, always the same result ==> it does not work.

I have controlled the configuration and observed that even by modifiying parameters in the global parameters page and saving, the modifications were not conserved. Then, I have found the parameters.php file and have modified it directly, indicating the right parameters.
In the log file, this is the last error message I saw:

Could someone help ?

I have searched within the forum but I have not found the solution for this issue.

2 - I have choosen Projeqtor because the functions allowing project management within Dolibarr were not developped enough. I saw that projeqtor is able to manage client/contact database, commercial proposals, invoices... However, I think that Dolibarr is better for this.

So, my second question is: has somebody already made a link between Dolibarr and Projeqtor, in order to allow Projeqtor collecting Client data directly from Dolibarr tables, Project informations from Dolibarr,.... ?

THanks in advance.
Thanks.

Yes, all has been verified. The e-mail adress is functional by using the webmail service (with same identification).

For Projeqtor API, I will search what it is and how it works...

Thanks
