Hi there, I've not been able to send any emails since Monday last week. I thought at first that it was just me but it seems to be an issue with a couple of my colleagues too (but not all) - it's very strange. I've bullet-pointed the issues below to break it down: • 3 staff members here can't send emails, but can still receive • 2 staff members remain unaffected • We have an email address (sales@directspecs.co.uk) that is on two computers. We can send emails from one but not the other. • All SMTP settings have been checked with the email service provider and all details are correct. • I've tried uninstalling/reinstalling Thunderbird to no avail. • We get intermittent "Unable to save the message as a draft" errors whilst typing emails. • The error that pops up on sending is just "Sending of the message failed" - no timeout error or anything of the sort. • We've spoken to our email service provider who are insisting it's not a problem on their end. • We've spoken to our ISP who are also saying there should not be a problem. • Our email provider is Bluepark • Our ISP is Optix We're completely at a loss of what to do now. I've tried looking at the error log and even when I get the "Sending of the message failed" error, nothing else pops up in the error log. Any help would be greatly appreciated. Thanks, Direct Specs
