Zoho + SMTP: Connection could not be established with host

[Willy15]

Dear all,

Happy new year!

Im facing some issues configuring my store email Zoho + SMTP.

My PrestaShop version is 1.6.1.12, but since I modified some core files, I'm manually updating every bug that has been reported and fixed until 1.6.1.17. I never touched an email file, though.

Server information: Linux #1 SMP Wed Jun 21 18:37:06 EDT 2017 x86_64
(Shared)
Server software version: LiteSpeed
PHP version: 7.0.21
MySQL version: 5.6.36-cll-lve
MySQL engine: InnoDB
MySQL driver: DbPDO
Current theme in use: pf_basic

Everything was working perfect, but a few days ago, my store stopped sending emails to customers, and everytime I try to send a test email, I get this error message:

Error: Please check your configuration
Connection could not be established with host smtp.zoho.com [ #0]

And I did not change anything before it stopped working...!
I contacted Zoho support asking for help. After some traceroute and OpenSSL test results, they found that eveything was normal; no issues in connecting to their SMTP server. So it has to be a store problem somewhere...

This is the guide I followed to configure emails:

https://www.zoho.com/mail/help/zoho-smtp.html

- Tried both, SSL and TLS (465 & 587) encryption.
- The email address matches the Shop email.
- Not using 2-step/factor verification.
- Not using a password with special characters.
- PS log and server error log not showing anything strange.
- I added the recommended Zoho SPF record in my webhost.
- Email address is the Zoho admin account.
- Also tried using same email/pw for PS login and email. No luck.
 

BUT........., I created exactly the same email account from my webhost Cpanel (and using webhost SMTP settings in PS) and it works!...

 

This is clearly not a solution, but a quick fix until someone shows up with a solution for Zoho SMTP settings error in Prestashop.
I've seen many similar threads, tried all solutions but they didn't work at all.

Any ideas?

 

Also, every email sent using the email templates from PS, has 1 attached file called "img" 0 KB... What is this and how can I remove it?

 

Thanks

Same here.

Local server for which smtp with gmail has been working flawlessly for years but suddenly it stopped with the same error as you : 

"Connection could not be established with host smtp.googlemail.com [ #0]"

 

Does anyone from Prestashop is aware of this ?

Im sorry to hear you're having the same problem...!

Not sure what is causing it, I even tried another webhost and it's not working either...

Just curious... What version of PS are you running?
