Hi,

What do you want to know ?

If your system is an abap Netweaver system, there is no permanent connection between the ICM and the STMP relay. The connections happen when the send mail job is running. You ca ndecide if this job parallelizes and so opens up several connections.

Hi olivier,

Thank you for your responce.

our system only opening too many SMTP connections and was reaching the defined system limits.

It seems that our servers were not able to reinitiate dropped connections.

Could you please let me know How to reinit those dropped connections properly?

We are using SRM 4.0.

SMTP connections and was reaching the defined system 

Go to SMICM and check the status of the threads on the ICM monitor.

You can set ICM to restart dead threads...

If the ICM is terminated (due to an error or by the administrator), it is automatically restarted by the dispatcher. You can control this behavior by choosing Administration -> ICM  -> Restart -> Yes or No. If you deactivate the restart and exit the ICM, it will not be restarted.

Hi Experts,

Could you please help me on this?

1.How is SAP handling connections to SMTP?

2.How can we avoid having too much connections opened at the same time and is there a way to automatically close/reinit dropped connections?

Any help on this urgently would be heighly appreciated.

Hi Suneel

1. you configure SMTP node in SCOT in SAP, and there you give SMTP server host or IP. Messages are sent from sap, os level sendmail service forward it to SMTP server and SMTP server forward it to externl email address (for eg if you consider and email send function to external email address)

2. To avoid heavy traffic, two SMTP servers can be configured and then in SCOT you can give host alias

instead of specific IP, so as to avoid failure situation of one SMTP host and congestion.

2. To drop or re-send the pending messages, you can use SOST.

thanks
