Flow probably recycled a blacklisted IP and you got the short end of the stick?
Can't force a new IP lease? Or request that flow sort it out?
Check your IP here, if it's blacklisted more than once, send flow the screenshot and ask for a new IP lease or some shift so

change your outgoing server port to 587.
then go to Outgoing Server Settings and Click "My outgoing server requires authentication"

Also check the box " Use same settings as my incoming mail server"

then do a test. this should work now.

^^^ what DFC said...

remember to allow said port through your firewall (if any)

I've encountered this same issue, I've tried all the above and sent from multiple IPs and different accounts. I believe the issue may stem from the recipient's server (as I only have this issue sending email to certain companies). Strangely enough the only workaround I've discovered is that I can reply to their messages though... So I recycle an old email in my inbox change subject etc. and it works, for me leastways *shruggs*

Bear in mind that's my personal experience, you can try the suggestions above and hopefully It'll work for you.
