If you successful authenticated yourself to the SMTP server you will see something similar to:
⋮ < 235 2.7.0 ... authentication succeeded > HELP < 214-2.0.0 This is cmsmtp ESMTP service help 214-2.0.0 This is cmsmtp ESMTP service help < 214-2.0.0 To contact postmaster send email to firstname.lastname@example.org. 214-2.0.0 To contact postmaster send email to email@example.com. < 214-2.0.0 For local information send email to Postmaster at your site. 214-2.0.0 For local information send email to Postmaster at your site. < 214 2.0.0 end of HELP info 214 2.0.0 end of HELP info * Connection #0 to host smtp.virginmedia.com left intact
however if not you will see: ⋮ < 535 5.7.8 Authentication Credentials Invalid (VM300) * Closing connection 0 curl: (67) Login denied What VM code do you see; in the example above it is VM300? Please do not be tempted to post more than the requested curl output as you will likely reveal your email address and password."
Can you please just post the error code which should be in the format VMxxx.

Re: Outlook 365 not syncing with smtp for outgoing emails
Well, my gmail account was ok initially, although now that my Virgin account has fixed itself I now get a repeated request for my gmail password which only stops if I open that account.
I think I'd better change my gmail password. I recently bought Office (Home 365) as I will soon need Excel and Word at home for work - I'm beginning to wonder if it's worth persevering with Outlook though. If I get more glitches I think I'll go back to Virgin's interface for that account and Microsoft for gmail.
