Emails being rejected with "550 suspect content"

Post by luisalonsoramos » Thu Jan 29, 2015 12:49 am

Hello,

One of my user reported that when sending an email to multiple recipients (all of them in BCC), most but not all of them bounced back with the following error:

==
MailEnable: Message could not be delivered to some recipients.
The following recipient(s) could not be reached:

Recipient: [SMTP:xxxx@demotechnic.com]
Reason: 550 Message Contains SUSPECT Content :: Please contact abuse@fortressitx.com for further information.
==

I tried contacting abuse@fortressitx.com to no avail, but after some investigation it seems that it happens when an emtpy To line is accompanied with many addresses in the BCC.

However I asked him to email me with only my address in the BCC and it worked fine.

Any ideas?

Thanks in advance,
