Hello,

My problem is simple. In Thunderbird, I have 4 accounts: one Sfr, one Laposte, another Free, and finally one Gmail.
Everything was going well; I was sending and receiving emails from all four. One day, I noticed that when I try to send from SFR and Laposte, I get the following message:

An error occurred while sending the email. The mail server responded: 554 5.7.1 Service unavailable. Client host 88.xxx.xxx.xxx rejected for spamming issues. Client address 88.126.108.105 blocked for spam incident; http://www.spamhaus.org/query/bl?ip=88.126.108.105. Please check the recipient's address ..@... and try again.

No issues with Free and Gmail.
My ISP is Free, and I have no trouble receiving my emails with all four.

Do you have any idea? Thank you in advance.

Configuration: Windows / Firefox 77.0

Hello Jac34,

"rejected for spamming issues" means that you are considered a spammer because too many recipients or too many emails sent

Change your account settings to send authenticated emails using SSL and your username = full email address from your ISP.

Hello,
I don't quite understand what you mean. I send my emails to two or three people.
On the other hand, in the account settings, I have
Server name: pop.sfr.fr, imap.laposte.net, imap.free.fr, imap.gmail.com
Connection security: SSL/TLS for all.
Does that mean anything to you?

Hello,

Use the Spamhaus form to remove your IP address from its blocklist, or get help from your ISP to do it:
