Mails send twice sometimes

[Borys Sobieski]

Hello together,

we are having some strange behaviour at the moment.
Sometimes when sending mails they are send twice to the recipient.

The “doubled” mails have the same message ID.

I am a bit stuck right now in the way of debugging this. Where to start, where to look at etc. and so I would like to ask if anonye has some hints for me.

Thanks in advantage.
Borys
