For several years, Mike Woolsey of Solutions by Design maintained a list in the Business Partner Forum of the various known or guessed limits in Notes/Domino. He graciously agreed to allow this list to be distributed to any Lotus Customer, and I have decided to post it here and try to keep it up to date. This is the R4 list, while the R5, ND6/6.5 and ND7 lists are on the Domino Limits page. If you see values which seem incorrect to you, post them as comments to my Limits in Notes/Domino blog entry and I'll update the information I have after I verify what I can. Feel free to link to this page or to the blog entry, and I'll make sure it stays around.
If you know of any errors in this list, let me know.
Anyone knowing more limitations, please let me know (see blog entry above) and I'll update this doc. If I miss a limitation you mention elsewhere, let me know.
