@peopleinside the issue was resolved by commenting out the code block in the function, assertValidAddress() located inside
vendor/swiftmailer/swiftmailer/lib/classes/Swift/Mime/Headers/MailboxHeader.php
I do not know if what I did is the right way to go about it but it works for me and I wish to share it with the group.
Here is the screenshot of the code block in the function that was commented out.
Can you tell us which email service are you using & also which UVDesk version are you using?
@vipin the UVDesk version is v1.1.0 and am using office365 email service.
The error is saying that the email address you are providing does not comply with the RFC standards. Make sure your email address variable is not blank.
The fully RFC 822 compliant regex is inefficient and obscure for validate email address because of its length. Fortunately, RFC 822 was superseded twice and the current specification for email addresses is RFC 5322. RFC 5322 leads to a regex that can be understood if studied for a few minutes and is efficient enough for actual use.
If you use HTML5, use this code:
<input type="email" name="email" required placeholder="Enter a valid email address">
