Zabbix cannot send e-mail alerts (unexpectedly)

[storm1kk]

Hi all,

I have updated my Zabbix 2.2.3 to 2.2.6 and it doesn't send e-mail alerts now.
I have the next message in Administration->Audit->Actions:
cannot connect to SMTP server [IP_ADDRESS]: cannot connect to [[IP_ADDRESS]:25]: [22] Invalid argument.
I have tried to re-install, unsuccessfully, the same error.
In Zabbix logs the same error.
How can I fix it?
SMTP server side seems OK, I can connect with telnet.

Thank you in advance!
