ERROR: Send SMTP Mail Message: Index was outside the bounds of the array

Hi all,

I am getting this error at Send SMTP Mail Message activity and do not understand why getting this.

Because in this project, robot sends a lot of mail stage by stage. It send nearly 100 mail last few days but do not send this one.

I got it. It is gettig error because of this split code.

And it should split this word: DUNYAEKOBASIMYAYINVEDAG.TIC.SAN.A.S. DUNYAEKOBASIMYAYINVEDAG.TIC.SAN.A.S.

It is getting error because of there is only one single word. But the code try to get first 2 word of this.

How may I edit this code to work in situations where a single word will come?
