magento2-gmail-smtp-app's Issues

Invalid Sender Data

Previous issue was I couldn't complete orders because of an invalid "Mail FROM" error coming back from Amazon. I fixed that issue by just using Google Apps, so that no verification was needed.

But with Google Apps I cannot verify customers. Our store is set that new customers are just pending and must be approved since it's primarily a Wholesale site. So now when I click to approve a customer it emails that customer that their account has been approved. But I can't approve any accounts because it comes back "Invalid Sender Data" when trying to send the email.

So with Amazon SES everything works excepts orders. With Google Apps Email, everything works except approving customers. So I guess we can have a store that doesn't allow orders, or doesn't allow customers. LOL

Stopped working after zend mail security update

Zend Mail framework update apparently kills it.

2. At System > Web Setup Wizard > Component Manager nothing is visible after sync

E-mail test works but nothing else is sending

Hello. I have just installed this extension and set up my configuration for Gmail apps. I did the test e-mail and it works, but actual transaction e-mails aren't being sent. Is there an additional configuration I need to set somewhere? Thanks.

Test email is working but no other emails send.

Today I installed the extension and after configuration I'm able to send succesfully the test email.
Unfortunately no emails are send via the Contact Form and also no Transactional Emails.

Cleaned the cache many times but nothing helps.

Strange thing is that the GUI shows the message 'Thanks for contacting us with your comments and questions. We'll respond to you very soon.' after the Contact Form is submitted.

Before I installed this exstension I had the standard email option enabled and saw mails initiated. This gives me the impression that in priciple Magento itself is configured properly, /home/xxxxxx/.php/php-mail.log shows:
[03-Jan-2017 21:03:47 UTC] mail() on [/home/xxxxxxxxxx/public_html/vendor/magento/zendframework1/library/Zend/Mail/Transport/Sendmail.php:106]: To: xxxxxxxxxx -- Headers: From: xxxxxxxxxx Reply-To: xxxxxxxxxx Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Content-Disposition: inline MIME-Version: 1.0

My configuration is:
Gmail Smtp App v1.4.0
Magento version 2.1.3
PHP Version 7.0.13

Can not install it on Magento version 2.1.2

Hi there,
I am unable to install it on Magento 2.1.2.
I am using this command.
composer require magepal/magento2-gmailsmtpapp

Please help

Amazon SES

Hello,

Can you provide some guidelines on how can I make this work with Amazon SES?

Thanks,
Mian

when save config. then can't send mail.

php7.07 magento2.1.2
if don‘t save config,it's ok.but,when save config,then can't connect the smtp server.
it's seems the password can't save.if save then bug.

Plugin doesn't support PLAIN connection type to SMTP

May I ask why you doesn't support this type of authentication?

Warning: include_once(Zend/Mail/Protocol/Smtp/Auth/LOGIN.php)

Thanks for this module. Install looks fine, I'm able to enter my credentials in Store/Config/Advanced/System, but when I try to send an email I'm getting this error:

main.ERROR: Warning: include_once(Zend/Mail/Protocol/Smtp/Auth/LOGIN.php): failed to open stream: No such file or directory in /var/www/magento2/vendor/magento/zendframework1/library/Zend/Loader.php on line 134

No port specified so defaults to 25

Although you mention that port 25 is not used, there is no port specified in the code, so port 25 will be used, with any throttling, blocking etc. that may come with that, especially on AWS

I think the change to support a port would be simple, as the port just needs adding to $smtpConf in \MagePal\GmailSmtpApp\Model\Transport.

Blocking Orders from being placed

So I've installed this and it seems to work really well. I've been testing it and emails work fine. Forgotten password sends off an email. Changing a password email goes out.

But then I try to place an order. If you place an order from the frontend it just says that the order failed. And I had no idea what was causing it. But then finally I placed an order from the admin and it came with a more specific error "Invalid MAIL FROM address provided". So I realized it was this module. Disable this module and I can place orders on the frontend and admin.

I don't understand why it's getting this error though. I've verified the domain and several emails in Amazon. Not to mention emails are sending just fine. Everything except order emails. This will not send an order email at all, and prevents any orders from even being placed.

I've played with what little settings there are such as Set Reply to, Set Return Path, Set From. And none of the settings change anything whether it's Yes or No.

Is there some log I could be checking? I don't even know what email it's trying, and why is it different than every other email that goes out? Maybe I can change the Order email some how? Although all the Magento from emails are set identical and it's verified in Amazon. Seems to be something strange going on, any help would be appreciated.

Multisotre: Mail send from backend(change status, comments) are send with bad domain

Hello,
We have setup Magento2 with Multistore on two saperate domains with gmailsmtpapp.
If client make order from domain1.com then mail came from domain1.com ( this behavior is OK.)
But if Administrator log to backend http://domain2.com/admin/ and navigate to orders and change somthing in customer order from domain1.com then client get mail from domain2.com(witch administrator is logged) ( this behavior is bad).

I think sending e-mail to customer from backends should be independend on domain where administrator is log in. Customer should get mail from domain1.com where he make order.

What do you think about this?

Saving SES password seems to fail

Hello,

When I change the admin settings, I can send a test mail. After saving however, mailing doesn't work and when I try to send a test mail again, it says bad auth. Magento 2.1.2. php 7

Does not work ...

Hello,

I found this idea awesome but I can't make it work !

I tried twice with the following credentials:

• SMTP with an email address from OVH (port 587) [I should use STARSSL thus I think it comes from this missing parameter]
• SMTP with a google account (port 465, I tried with "smtp.googlemail.com" and "smtp.gmail.com") but it does not work as well

Do you have any idea to solve this ?

I really think that this is a great plugin

Best

Matt

Full SMTP

Hello .. Good evening

Could Not Open Socket

I tried to configure my gmail account for sending emails on my Windows machine. But when sending test email, it gives following error: http://joxi.ru/V2VBaKvh0oXK62

Here are my configurations: http://joxi.ru/Dr86vE9uk8LM62

I have enable Access for less secure apps in my gmail account: http://joxi.ru/E2pdVgnfBNpGN2

My PHP streams: http://joxi.ru/krDO8Dkt0jy4QA

Is this something related to my gmail account?

Thanks

NOT AN ISSUE...

Hello,

Just thought I'd suggest to whoever manages this repo, that this extension works perfectly with Microsoft Office365.
Notes to make it work:
Auth Method: Login
SSL Type: TLS
SMTP Host: smtp.office365.com
Port: 587
Username: [email protected] (replace donotreply with an ACTUAL licensed account in O365)
Set Reply-to: yes

in Office 365:
Set up an exchange connector from "your organization's email server" to Office 365, and specify by IP, and add your Magento 2 servers public IP.

Lastly: Make sure any other email addresses you want the [email protected] to send as, that THOSE accounts have the [email protected] address in its send-as field.

Feel free to add this to the Front Page Wiki.

Can this app be used as send-only email from website without any other server such Postfix ?

Can this app be used as send-only email from website without any other server such Postfix ?

I have 2 domains hosted on Godaddy, Godaddy has my DNS.

In DNS I pointed both webistes to my VPS ip and installed two Magento 2 websites.

I pointed mail to yandex, so my email for my domains are via yandex mail servers.

I installed this magento2-gmailsmtpapp to both of my magento 2 websites. Configured everething and each domain sends emails as expected.

As an experiment I removed Postfix and Dovecot from my vps but this app continue to work on each of websites as usual ! How that can be? Is this app acts as a send-only mail server?

I scanned the ports and looks like port ( 111 portmapper, rpcbind ) is open, is this related to this app?

Questions 1: Can this app be used as send-only emails without Postfix?

Question 2: In this app can I add DKIM or SPF to each of domains? Thank you

My config:
Centos 7
PHP 7
Mysql 5.6
Apache 2.4

Can't Save the Customer

So I had a problem that I thought was relating to other plugins. But customers can't save, and Pending Registrations won't process, all because of email being sent out. I thought it was because of this plugin first, but then when disabling something I thought that the problem went away, so I thought it was other 3rd party plugins. But it's not, after doing further research and disabling all the other 3rd party plugins I'm seeing the same error. And after tracking it down further I'm seeing it's directly relating to this plugin.

When trying to save a customer it keeps coming up with an error that it can't save the customer from the front end, or from the backend it was creating the customer, but showing an error about the email.

When creating a customer I get this exception:
