Gmail fix or alternative

[rick]

Good morning everyone!
I have a few customers using Gmail for their voicemail to emails. It used to work everytime, but in the last year or so t works - them fails and its become a pain.
I have the 'less secure apps' allowed and the Gmail SMTP details, but like I say, it works for a few occasions then fails again and again.

Does anyone know the fix for this? Somethiong that works and stays working or is there an issue with Gmail itself working with the 250?
The customers I have with Office365 work easily - But is there an alternative smtp email server/system that is free but works for this purpose that anyone know of? (aol? Yahoo?)

Thanks

Most ISP's give anywhere from 1 to 20 email addresses with business Internet service, or charge a minimal monthly fee... We use those in many circumstances, often within their own network encryption, and sometimes even login credentials, are not even required.
