error to send email to a domain "initial server greeting"

[fferraro87]

Hi,

some of my users cannot send email to this domain bricofer.it , they have this error :

Code: Select all

<helpdesk@bricofer.it>: lost connection with
mail.bricofer.it[185.41.215.201]
while receiving the initial server greeting 

So i try to contact 185.41.215.201 on port 25 with telnet but i don't have any banner in response

Code: Select all

[root@lev-mail-01 ~]# telnet 185.41.215.201 25
Trying 185.41.215.201...
Connected to 185.41.215.201.
Escape character is '^]'.

so if i don't see any greeting banner mean that 185.41.215.201 has a problem or there is a problem on my mail server?

Thanks

It works fine for me:

Try a connection using one of the (many) internet test services such as mxtoolbox.com. Do you have any anti-virus or any other service scanning your systems? Perhaps it's something on your firewall (if you have one)? In any case I'd suggest this is a problem local to your server and/or network or it could also be a problem of the Transaction Time (i.e. how long it takes to connect & respond).
