as of this morning, I'm getting this error also.
I can't send ANY mail - not even a message that consists of the single word "test".
Solved! Go to Solution.
On my desktop, using Webmail, I get Error 53 for all send attempts. Same result using either Chrome or Firefox.
On my desktop, using an email client, I can't send either (dont see error 53 as its shielded by the client).
On my Android mobile, I can send.
I can receive ok on all platforms.
This has never happened to me before. In fact, its the first problem I've had with mail in ages.
Hi @msd123 Thanks for confirming that, I'll send you a private message so you can send over your details and we'll get our email experts to take a look.
Thanks
Neil
Following a "change to the filters" by email support, the problem has gone away .
It sounds like my IP address may have been (accidentally ?) flagged as a spam source.
Thanks for the help 😀
