Hopefully it will stay good. But just to let you know that the error 554 5.2.0 Sender Denied (TT608) 554 is a transaction failed error because TT608 means there are concurrent logins to your mailbox detected from multiple geographically distanced locations. It's a spam protection measure because the TalkTalk system thinks your mailbox may be compromised.

Use of an overseas hosted VPN server at the same time as a direct connection to the mail server could cause this as a false positive. A compromised password could be the worst case scenario.

Thanks very much gondola. It's my fault then as I have overused it today from various devices.

OK, that does feel like it's a false positive which is comforting.

If the TT608 stop on sending does happen again then it'll be something like making a connection from work at the same time as leaving a home connection active or using a mobile via a VPN etc. It's multiple concurrent connections to your mailbox from geographically distanced access points that the TalkTalk system picks up on.
