Hi,
my SMTP seems to have stopped working some time ago, and my invoiced now are coming from noreply@quickfile.co.uk ending in recipient’s spam folders.
When I try to reconfigure my SMPT I get a timeout error. I am sure the settings are correct because I use the same ones for my email client, and I have double-checked them on mail.zoho.com (my email provider) website.
I have also added SPF record (include:spf.quickfile.co.uk) to my domain DNS just in case (domain managed by namecheap.com) but it did not help. I still get the timeout error.
You may want to open a ticket with your mail provider to see if they still have our IP range (5.2.17.178-190) white-listed. This would normally be the reason why you’d suddenly encounter a timeout issue when there has been no change to the underlying credentials.
EDIT:
The SPF record won’t have any affect on the SMTP time-out, it will just add a record to your DNS that any recipient can lookup to tell them it’s OK for your mail to arrive from our servers.
I did a quick check on your mail server and it’s not responding at the moment:
Thank you, I will contact them. I have just sent a test email from this account from my email client and it worked without any problem, so I am not sure why mxtoolbox shows it not responding.
